Custom LED Fog Light Install for the Fiat 500c

We recently came across this custom LED fog light install for the Fiat 500c and thought the results were great. The Fiat owner used the GTR Lighting 9W LED Projector Driving Lights and a GTR Lighting halo switch. Below are the step by steps for the install and the final product.

After considering the Fiat option fog lights for auxiliary lighting; I decided to go a different route and go with an LED setup. The other LED setups I have found were either square lamp units or rectangular. I wanted to stay with the “round” – “circle” theme that our lovable 500s currently posses.

Decided on the GTR Lighting LED driving lights. The lights are rated @ 9W, 600 lumens with a 6000K color rating.

The install required the front bumper to be removed.

After removing the bumper (with 8 Pozidrive screws & 9 T30 screws) the blank foglight covers can be removed (attached by 4 tabs each). Once removed – A 2.5″ hole cutter was used to provide an opening for the new light units.

A mount was created from the rear of the foglight opening from aluminum plates and secured by 4 bolts. The foglight openings of the bumper only had 3 mounting holes, a fourth hole had to be created to provide a more stable mount for the aluminum plate.

The driving light units came with mounting holes @ the rear. I used M8 x 1.25 bolts to mount it to the aluminum plate – the length of the new bolt allowed depth adjustments. The depth is adjusted with the use of fender washers and 2 nuts that sandwich the Al plate.

Depending on the preference, the bolt (along with the light unit) can be moved forward or back.

12V and ground were tapped from each of the stock DRL bulb holder / wiring harness. The wires needed are Orange (+) and Black (-). This retains the on/off functionality when the turn signals are activated. I did install an auxiliary switch to turn off the LEDs and allow the stock DRLs to stay on.
