I really like the brightness and quick off-on cycle of LED third brake lights you see on late model cars and trucks. I did a little research on the web and found that you can buy LED conversion bulbs in common sizes for cars like 1156 and 1157. There's a company out of California called Ledtronics that makes a ton of LED's for almost everything. They sell 1156 conversion bulbs (at a rather high price) https://www.netdisty.net/ds/aut1157/Default.asp and there's this guy on eBay also selling them http://cgi.ebay.com/ebaymotors/aw-cgi/eBayISAPI.dll?ViewItem&item=1809376331 . I thinking of buying a pair of 1156's to use as stop lights on my W123. Has anybody here tried these LED bulbs?
