The seller is Jap on here

They are easy to wire up, etc., just that mine didn't work

Glad in a way though, as there isn't enough room behind to fit the bulbs/lens in properly and they stuck out too much and I didn't think they looked good.
They may not of worked, as the led legs, no matter how much I moved them out of the way, just didn't seem to have room and I think they may have been touching metal, causing them not to work.
I didn't test them first, so don't know if they were working before I put them in or not.
It could be done, if someone who knows what they are doing, has a lot of patience and time to get it right.
I have none of either, so tried it, didn't work, looked sh!t, so abandoned the idea.
I may try again one day if I can be bothered, or if I have to if I get pulled by a copper for no side repeaters, but until then, I'll be leaving them alone
