Old foglight project


Recommended Posts

When I bought my car it had 1 amber fog light on it. I took it off and threw it in a box.

Today I decided to turn it into a rear fog lamp.

I painted the amber lens red with a product called Night Shades from the local auto parts store. I also got a bulb socket and small bulb. The original bulb was a H3 so it would to too bright to shine in "most" people's eyes.

I did some cutting on the socket and got it installed in the housing.

The light looks great and is about as bright as my brake lights. I think I will wire it to come on as a 3rd brake light.

that's a cool light. Seems like using it as a 3rd brake light would be more useful than a fog light - or maybe you could use it as both? Post a pic of the final mounting pls, and wiring mods!

Interesting project, but I wonder if you have enough light from a 194 bulb (rated 2.0 mean spherical candlepower, MSCP, or 25 lumens) compared to a typical stop or turn bulb used in a red rear foglamp, such as a 1073 (32MSCP or 402 lumens).

One option would be to use a 10 Watt halogen bulb with a miniature bayonet base (note, the socket must withstand the halogen temperature!); see attached. It is rated 200 lumens and generates much less heat than the H3 bulb your lamp was designed for.

Another possibility is to use a red LED bulb (I have used some from [http]). The red LED's are fairly monochromatic, so the lens color does not matter. And without a red filter absorbing 50-90% of the light output, an LED bulb does not need so many lumens to create a light output similar to a 32MSCP bulb. While for a typical LED retrofit I am very concerned about enough candlepower in all important directions (not just straight back), a red rear foglamp is a non-mandatory option so about any candlepower distribution would be a benefit.

Good luck!

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
