RE: Lights on my GST...
any bumper the size of your truck will work if it can be mounted. i had an old radio shack hummer that had problems so i stripped it and took off what i could use...including the front and rear bumper.."with dremel" I cut the bumper just right so i could screw it to my traxxas stampede then incorperated the lights...slot car lights from the hobby store and leds from radio shack...and ran them directily to the aux on the reciever. Any old model..or even an 15 or so dollar model with a bumper on it with places to put LEDS wiill work
