What are these European sidemarkers? Are they the ones right in front of the front door that have been on Subarus for a number of years and are now starting to appear on other models? I'm sure you could add them if you wanted to.

Working for a local BMW dealer, I have had experience with all of the things you mentioned. Xenon is a more focused beam. As I was told on our cars when you first turn them on, it strikes a 40kv arc to produce light and after that the voltage goes back down, pretty cool stuff. Side markers are readily available and are already coming on the new cars. The "man" is not going to a ticket for having added extra lighting, especially when the newer automobiles are coming with them standard. Production cars are coming with "LED" lights. Neon too... Don't quite understand your question on the H4's. Some cars offer both of the wipe/wash systems you mentioned, however I think cost is the major deciding factor. You can get them as anb option..

Good luck, Chad

Side marker lights, you can purchase an universal side marker lamp from an "import" performance shop and wire them to your turn signals.

LED rear lamps: The Caddy Deville was the first car in the US to offer LED rear lamps. BMW (7-series), Nissan (Infiniti G35), & Mercedes (S-class) has followed also. LED's have been in usage on commerical trucks and buses for a number of years also (before the application on a car). Neon lighting was used on the 1996 Lincoln Mark VIII for the center lighting. Brakes lights still used the convention bulbs. It was also the Lincoln Mark VIII, a reflection HID system was used. (BMW was the first in HID usage, period -- projection system)

HID Lighting: DOT regulations call for a self-leveling unit of the aim to be installed in OEM applications. ECE regulation regular the levelers AND headlamp washers.

Increased light output on H4 lights for example: According to some companies, what they do it alter the gas mixtures, increase the gas pressure, and modify the filament produce more light output. This may also decrease the life.

Headlamp washers instead of wipers: It's cheaper, it's cheaper, it's cheaper (and less components to break). I believe Volvo still uses the wiper system on some of their cars.
Hope that helps a bit

Is there any possibility that I obtain side marker lamp european law regulation to put on a car?

Yes. Under ECE Regulation 48, front and rear sidemarker lamps are permitted, but not required, on passenger vehicles. Sidemarker lights conforming to ECE Regulation 91 may be fitted to any motor vehicle without supplementary approval permissions. They should be installed in compliance with all applicable provisions of ECE Regulation 48 concerning mounting location and electrical wiring. Under ECE Regulation 48, all sidemarker lamps must produce amber-coloured light; the rear sidemarker light may produce red light if it is grouped, combined, or reciprocally incorporated with the vehicle's main rear light cluster.

NOTES:

1) This colour requirement differs from the North American regulations in force in the US and Canada, which [ul][li]Requires all vehicles to be equipped with front and rear sidemarker lights and retroreflectors, and [li]requires that front sidemarker lights and retroreflectors be amber, and rear sidemarker lights and retroreflectors be red.[/ul]

2) Another individual in this thread has confused sidemarker lights, which you asked about, with side turn signals. Side turn signals, which never burn steadily but simply flash in phase with the turn signals, are required under ECE Regulation 48. They are permitted, but not required, under North American regulations.

3) ECE R91-compliant sidemarkers are manufactured in various styles by Hella of Germany. See their sidemarker page,

Can avoid the side marker lamp an accident?

The North American authorities seem to think so, and they're probably right. Sidemarker lamps increase the vehicle's conspicuity from the sides. It must be said that the North American system of mandatory amber-front and red-rear sidemarkers gives the advantage of providing a clear visual signature to observers from the side of where each car starts and ends.

Why today rear lamps are not offer on led technology?

Some few cars are beginning to use LEDs and other non-filament technology (e.g. Neon) for signalling functions. It offers several advantages including rapid rise time to full intensity, homogeneous appearance when lit, and minimal depth requirement for minimal intrusion into passenger or cargo space. However, it is also considerably more expensive than bulb-type units. LEDs are highly directional sources of light; therefore, a great many LEDs or very complex optics are necessary to spread the light through the legally-required wide vertical and horizontal angles of visibility. This is not an easy task, but it is getting easier and less expensive as better, brighter, and wider-angle LEDs come down the line. We see many more commercial vehicles with LEDs than we see passenger cars with LEDs because commercial vehicles use only a very few standardised-format lamp units, so the economies of scale make it worthwhile to produce them.

Several BMW, Mercedes, Opel, Cadillac and other models are presently using LEDs for signalling functions.

Xenon Headlamps are they more power than halogen headlamp?

It is common but incorrect to call them "Xenon" headlamps. There is Xenon gas in the burner, but it is there only to provide a minimum level of light immediately upon turning on the lights, as required worldwide by regulations. The lamps are actually metal-halide High Intensity Discharge lamps (HID). The light changes from dark blue-purple to bright white over the course of 60 seconds after startup as the metal salts (halides) vapourise within the burner.

The HID burner is much more efficacious than most halogen bulbs. That is, it produces much more light using much less electricity. However, this is a source factor only. It does not mean that all HID headlamps are better than all halogen headlamps. The effectiveness of the headlamp is a function of its photometric performance (beam pattern), which is affected but not determined by the light source. There are certain halogen headlamps that are better than certain HID headlamps, and vice versa. ECE Regulations 98 and 99 prescribe more stringent minimum performance requirements for HID headlamps than ECE Regulations 112 and 113 prescribe for halogen headlamps; US and Canadian regulations treat all headlamps the same.

There is a great deal of marketing hype surrounding HID headlamps. They're not a scam, but a lot of what is said in an effort to sell them is simply not true. Their light output is not "closer to natural sunlight". Their beam pattern does not necessarily give you extra safety. Good headlamps are better than bad ones...and that's all that can be said about that!

How can obtain the companies more light on an H4 Halogen Premium lamp than in a H4 standard lamp?

You are asking here about the newer "Plus 30" and "Plus 50" versions of older bulb designs (e.g. H1, H4, etc.). There is no magic here; H1 was the first automotive halogen bulb, introduced in 1962. H4 was the first dual-filament automotive halogen bulb, introduced in 1971. Since that time, there have been advances in the science. The higher-efficacy bulbs achieve higher luminous flux and luminance with filaments wound on smaller mandrels. This creates a smaller filament coil that more closely approximates the point source upon which most headlamp optics are calculated, moving actual performance closer to the theoretical potential of any specific headlamp design. The filaments are more precisely focused within the bulb, and the gas fill is more advanced; usually with a higher proportion of Xenon and some other constitutents. This allows the filament to be driven harder without premature failure. Because ECE Regulation 37 (and US FMVSS 108) gives a fairly wide tolerance for allowable light output from each individual bulb type, there is room for increased output without falling out of compliance with the standard. As long as the bulbs you're considering have a clear glass, and not a colored glass, they cannot worsen the performance of your headlamps and will usually improve it.

Why now all the cars offers only headlamp washer system and not headlamp wiper/wash system?

Because ECE Regulations prohibit the use of headlamp wipers on headlamps having plastic lenses. Since polycarbonate plastic is becoming the favored material for ECE headlamp lenses, high-pressure washers are replacing wiper systems. If a washer system is well designed, it can be reasonably effective. The wipers can sometimes do a more effective job than a not-very-well-designed washer system, but they are more complex and costly to produce, and they can have problems freezing with ice in the winter. This latter problem is especially serious with HID headlamps, which do not produce enough infrared light to melt snow, ice and frost from the front of the lamp.

Hope this helps!

This is not correct.

What you refer to as "DOT regulations" are the US Federal Motor Vehicle Safety Standards and their nearly-identical Canadian counterparts.

There is no requirement in North America for automatic levelling systems to be installed on any vehicles with any kind of headlamp system at all. This, and the lack of aim declination linked to headlamp mounting height, are gross omissions from North American headlamp regulations. The auto levelling requirement is present in European ECE regulations. Some North American-market vehicles with HID headlamps do have auto levelling systems because they are required in Europe.

No.

LED signal lighting really is not a "retrofit" item in the sense
you're thinking of. The rear lamps of your car rely on a point source of
light (glowing filament), collecting that light with a parabolic reflector
and dispersing it with pillow optics in the lens. An LED is a vastly
different *kind* of light source. Unlike a glowing filament, it does not
produce light in an even sphere. Instead, it projects a very narrow beam
of light in ONE direction. That's why these so-called "LED retrofits"
consisting of a 1" diameter matrix of LEDs on a bayonet or wedge base are unsafe; there's no way you can get enough light through a wide enough
angle (horizontally and vertically) to create a safe and legally-compliant
lamp -- even with Ledtronics' clever radial LEDs, the performance just isn't there. There are other considerations, too -- it is tricky to get the
right ratio of bright-to-dim intensities both on axis (straight behind the
lamp) and also through the entire vertical and horizontal beam spread.

Look at the optics of the Cadillac DeVille that has Hewlett-Packard LED
tail/brake lamps, or the high-end Mercedes S-class that has LED brake
lamps. You'll see some *very* fancy optics used to coordinate the light
from a *LOT* of LEDs to get everything right in terms of brightness in
both dim and bright mode, uniformity of brightness throughout the
visibility angles required by law, ratio of intensity between "bright" and
"dim" mode, etc. These kinds of optics are not something you can kludge
in your garage, let alone achieve with these unsafe "retrofits".
