I am running the Wisamic LED inserts with the Halo wired to the sidelights. E marked and I think I paid £112 for the pair, delivered. Had them adjusted prior to the MOT, passed with no issues at all. They give a nice flat beam and I don't get flashed by every oncoming car (as I used to with the LED bulb only solution). In the pub car park test my halos were brighter than quite a few other 7's dipped beams. Halos are wired into the sidelight circuit, using the red wire only. The black wire needs isolating with some tape. Garry
