I spent some time today getting my LED rock lights installed on my Toyota FJ Cruiser. The LEDs are 1 watt and I installed 5 of them under the FJ. They are wired into a relay under the hood that is controlled by a switch in my switch console. I could have wired these directly from the switch with no relay due to the low current draw. However, the wiring system is designed to handle Halogen lights if I ever want install them.

Here is the LED that I sued. They are built into an aluminum housing:

This is the LED installed in the front wheel well:

Here are some night shots of the installed system:

The LED system works great. After some use I may need to shift them around a some to get a little a little better coverage up front. I also have 2 additional LEDs on the shelf to fill in the areas that still need additional light.
