Just wondering if putting Euro rear lenses on USA fixtures with active sidemarker is USA DOT compliant. The Euro rear lenses have amber turnsignals which should be acceptable. However, the USA fixture has a sidemarker bulb which is red with the US rear lens and amber with the Euro lens.
This sentence was copied from a description of lighting: "In the United States, the lens of a side marker, made of high impact, translucent plastic, is amber-colored for the front of the vehicle and red for the rear." And this one: Effective January 1, 1968, all passenger cars built for sale in the United States were required to display amber lights or reflectors on the sides of front fenders, and red lights or reflectors on the sides of rear quarter panels. From Washington State Legislature: RCW 46.37.100 Color of clearance lamps, side marker lamps, backup lamps, and reflectors. (1) Front clearance lamps and those marker lamps and reflectors mounted on the front or on the side near the front of a vehicle shall display or reflect an amber color. (2) Rear clearance lamps and those marker lamps and reflectors mounted on the rear or on the sides near the rear of a vehicle shall display or reflect a red color. The LED boards that I make have amber sidemarker LEDs for amber rear turnsignals. It makes me wonder if the amber sidemarker LEDs should be shut off or constructed with RED LEDs. Thoughts? |

So did Euro 914's which were manufactured with amber turnsignals have a sidemarker bulb at all?
I'm tempted to build a set of amber turnsignals with red sidemarker LEDs to test out how well the red comes through the amber lens. |

To my knowledge, the EU cars do not have the rear side marker bulb in. It would be consistent with the fact that there are no side markers in the front. Please run a test with red LEDs for rear side marker to be used in combination with amber LED for the turn signal. I have been lurking at your products for a while now and would definitely appreciate that option. (IMG:style_emoticons/default/beerchug.gif) |

Thanks Mark, I have euro lenses on my 914. I tested a red 911 sidemarker board that I make. It has 12 LEDs on it. I placed the 914 lens from my car in front of the red LEDs measuring light through both the amber section and the red brake section. At 1 meter, I measured 27Lux though the red brake lens and 32Lux through the amber section. How about that? The red LED gave more light through the amber lens than the red lens. And the light through the amber lens was indeed red as projected on the wall. Based on this test, it would seem one could run red LED turnsignals through amber lenses. I will start making the amber turnsignal boards with red sidemarker LEDs which will be compatible with DOT specifications. I'm going to post this same topic on Pelican in my LED brake thread since the same thing is going on in the 911 with euro rear turnsignals. |
