I'd love to replace my taillight bulbs with LEDs for two reasons: the electrical savings and the super long life of LEDs. At least as long as they were BRIGHT LEDs--at LEAST as bright as the OEM ones. I've got a LOT of extra lighting already, front and rear, including Hyper-Lites. I'm a true believer about it.
I actually bought a product a few weeks back that I thought might do the job; it was an LED cluster with a standard base. Had a chance to buy it so cheaply I thought I'd take a chance. Half of the bulbs lit up in running mode, and the rest came on with the brakes. BUT--when I pulled the taillight out thru the mounting hole behind the seat (and connected the LED to the plug to see if it worked--and it did), I realized the cluster itself was too damn big to pass through the mounting hole and fit into the cavity behind the red lenses. :angry2: I gave it to a friend with a cruiser.
So I've still got my eye out for an LED replacement with an 1157 base and an 1157-sized head as well. Anybody got one?
