I bought a small 5 LED "click light" for the trunk on my 1500.I tried a 2 part epoxy that did'nt hold,then I tried hot glue which held for a while,then the light fell off. I did clamp the light overnight.What kind of glue will hold on the underside of the trunk? How about this unseasonably warm weather here in northern Illinois? Alot of the road work is done,so I went out for a couple of hours just for fun.The weatherman said it was 74 here and only 70 in Phoenix!
