LED Foglight Project Options

[Spoke]

The design of an early foglight LED board has begun. mepstein sent me a couple of foglight fixtures to use to design the board. 2 main issues are fitment and heat dissipation. If things work out ok the design should be able to be re-laid out for the later square foglight.

The board will have 8 Cree XP-G3 high power surface mount LEDs with 350ma current each. These will burn about 1W of power with a total power dissipation expected to be less than 10W. Hopefully these will be almost as bright as a headlight.

Each LED will have its own focusing lens. The lenses are Carclo 10192 elliptical 20mm lenses. The light pattern for the 10192 lens is shown below.



This is the spectral dispersion for the lens.

I'm totally supporting this. I drive at night 90% of the time, and my fog light reflectors are shot. I got a quote to re-silver at almost $100 each side. A quality LED conversion would give me my fog lights back.

If you want the best led headlights out there - in my opinion- its these trucklight 7” headlights. Very popular with the Jeep guys as well as motorcycle riders. There are cheaper options but a lot of times you get what you pay for. They take 10 minutes to install with no mods and are a total game changer. They make driving at night so much easier. They look a little odd but during the day the lights are down anyway. Even though they are very bright, I never get flashed because they have a very good cut off. The high beam is insane. They use less voltage than ordinary lights so are a little easier on our cars older wires and less battery drain.
