Pic shows return wire DOWN on left, UP on right. Second pic is trimmed bulb base. I used tin snips and a file, lots of other folks use a dremel. I was skeptical, but XD sent a pair of extra bulbs just in case I still wanted to return the kit. Lights work fine, no codes, no flicker, nice cutoff, easy to remove.If you have photos of where you notched it that would be great!
