Just installed PIAA Led driving light modules in factory foglight location.

As it says, I installed the Tacoma specific kit yesterday. They are bright and shine down the road nicely. The only thing is they do not come with a connector or adapter to plug into the factory body side foglight connector. They had male /female harness adapters in stock at Advance Auto for about $8.00 each. I soldered and shrink tubed to the light module and plugged into the factory plugs. I did the foglight anytime mod too and used the bent relay pin method. Very easy and I tapped into a parking light wire to trigger the relay. This is a big improvement in lighting. They go on with high beams or low beams if the foglight switch is enabled, off with truck off in any switch position.

 

I got them, try putting some yellow overlays on them and they become all weather lasers

 

I think my son has some of that yellow overlay. I'll check with him and try it. I just tested them and they are still aimed a little high I think.

The part number for the harness adapter is Techsmart F90006 Harness.
That was from Advance Auto. It has male and female connectors and about six inches of heavy wire.

 

im pretty sure they are a 3 inch diameter, I took a 3 inch coffee mug and traced it out on the film and cut them out with scissors, if you don't care for the yellow overlays you can just peel them off. I adjusted mine but I can still get flashed on back roads, also I got some radio static on weaker stations, but the driving beams are far superior than any foglights IMO

 

I'll try the film and see. I wonder how far out in front is optimal for the beam to drop to the road surface? It seems from the instructions that they are to be pretty much parallel with the road out to infinity.

 

use the instructions, these are drive beams not fogs, fogs pretty much light up the road surface in front of the truck.

 

I have them set per the instructions now. I did not get flashed tonight so I'll give it a few more nights and see how I like it. Thanks for the input Bill.

 

youll like them they are good auxiliary lighting that helps the headlights with extra illumination, using the yellow film tones down the white LED beam a lot so reduces the flashing for me but still cuts thru the dark,snow,rain better than the white light.

 

The PIAA lights come in 2 patterns, driving (high beam) and Fog.

You can see how the fog version compares to the competition here:

They are one of the most expensive and lower performing units compared to what is available from other manufactures.

 

Thank you for linking your research data here, very well done and informative. I agree from the data that the PIAA is a lower end performer. They are an upgrade from my factory halogens and luckily I did not pay full price for them. They really project down the road better than the originals. The harness was poor as noted and required additional connectors.

I wonder though about the general shift to the amber end of the spectrum in these newer lights. I believe the human eye is most sensitive in the high yellow to lower (nm) green wavelengths. That's why all that reflective safety clothing is in that color. That type of rainwear for example really stands out in low light conditions. I would think illumination in that area of the spectrum would enhance night/low light vision? Perhaps amber is beneficial in fog only? Those yellow driving glasses are also in that spectral range and really make the scene appear brighter.

I use my "fog" lights, on all the time , to supplement the very poor oem headlights. Sometimes in fog, even a fog light produces too much back glare. I have resorted to parking lights only at times of heavy fog ,conditions permitting. That was another drivers ed tip from the late 1970s.

Roof mounted lights are another thing. Has anyone ever driven in snow with them on? You can't see past the edge of the hood.
