This GM underhood light features a 20 foot retractable extension cord. The back of the light fixture has a magnet mounted on it for easy, no hands lighting. Just stick it anywhere you need it. Great for a flat tire, the cord is long enough to reach to the trunk of your car. When you're done, simply crank the handle to retract the cord back in to the housing. Mount it on your passenger side strut tower behind the alternator or next to your fuse box or on the underside of your hood (shown). Select from light only or include a handy wire harness to make connecting it easier.
