I pulled one expecting to find replaceable light bulbs but found a two pronged module instead. I've search the forums, parts house websites, and Google with no luck.
Anyone have a source for these?

 

should be able to get regular replacements at your local truck stop or big rig store... i got my LED markers at my local PETRO ... let me know i'll try to get ya a number if you want they were made by spyder though good luck!
