Does anyone have an opinion on bulb replacment for the C3? I have been using old Wagner H5006's for low beams. One has burned out and when I went to my local parts store I found that the replacement no longer has the nipple on the back to feed my fiber optic line. I can try one of the newer (i.e. cheap) bulbs and see if it puts out the required light in the back, but I am also curious about modernizing the bulbs. If I went with one of the new "diamond cut - increased output" halogens that are "supposed" to be direct plug-and-play replacements, will this again defeat my fiber optic system? Any options would be greatly appreciated.
