Here is the article I referenced. Ledtronics and Bright Lights make LED replacements but they are not as bright as an 1157 bulb, and about $26 a pop.
Ron Francis makes what they call Brite Bulbs, they claim as bright as halogens without excessive cost or heat. The 1157 replacement is 1077A and costs $6.95 each. Anyone have experience with these?
