I have about two dozen flashlights ranging from keychain lights to some 800+ lumen light cannons. It didn't take me long before I realized that my Telluride also needed lights. I started with the stock 4 LED light kit for the bumper, but that just wasn't cutting it. I added the Proline light bar kit with the lighting harness and LEDs from a Summit and now I'm happy!
The Proline kit is absolutely top notch. Normally with plastic pieces this small you get all kinds of burrs and things never fit properly. Not so with the Proline. Everything was perfect, though it did require some cutting to mount LEDs in the kit. It was also a little too big for the Telluride body so I had to rig up a new mounting system. I don't recommend it for a basher truck though. I did roll a few times and the light bar held up, but it won't take many more rolls. I would recommend it mainly for a show truck.
The lights work great and they're pretty bright. I would say they are putting out around 50 lumens total. I have no idea what their draw is, maybe I will get around to measuring it one of these days. I imagine it's pretty negligible. I didn't notice my run times being drastically shorter. My ultimate goal is to mount them on my E-Maxx with a 4ch radio system so I can turn them on and off from the transmitter.
