I read somewhere that you could replace your back-up bulbs (1157's) with the new 50 watt halogen bulbs from JC Whitney as they are 2.5 times brighter. Who doesn't want brighter back-up lites? Within 3 days one had burned out. I attempted to get it out but the solder slug on the bottom of the bulb had fused itself to the connector! Called Whitney and they sent me two new ones - free! Before they arrived the other one went out. I just got back inside from trying to change out to the new ones. Forget about it!!! Making sure they worked, I layed them on the housing and turned on the ignition; before I got back to the rear of the car they had already started to burn a hole in the plastic housing! No wonder they burn out, they are too damn hot!!!
Back to Whitney for my $14.95 back.
