Tom,
LED Bulb Info:
http://www.superbrightleds.com/cgi-bin/store/commerce.cgi?product=CAR
The best price I found was SuperBrightLEDS. For red tail lights part number
= Red1157-R24-Wide Must specify Red and Wide as default is White and Narrow.
Price is $7.49, Voltage limit is 14.8 vdc.
Order it wrong and it's yours, your fault. Bench check new bulbs on receipt.
They can be defective. Don't just bench test one, compare two for brightness
or bad pixel. High volume, they don't test. You test. Very short warranty
period. Vendor good to replace no charge including shipping with return
envelope for must return defective bulb.
