The Mk 1 versions weren't really bright enough in full sun. In the Mk 2 version I fitted two sequential indicators into the OEM housing, and as expected still not bright enough. Onto the Mk 3 version, I had a friend mill out two slots in the OEM lenses. After a little bit of fettling with a Dremel and files I achieved a good fit. I used clear silicone where the indicators fit into the slots and used a hot glue gun to glue the lower one to the bottom of the lens then glued the upper to the lower one with additional gluing at the entry point. A portion of the bulb holder surround had to be removed in order to allow access. As an added precaution I packed the area around the indicators and the back of the housing with heat proof foam.
Initially I had the heat sinks inside the rear indicator housing, however I spent yesterday and this morning moving the heat sinks to a more suitable position on the rear frame rails under the start of the ducktail. The heat sinks do heat up quite a bit and I didn't want to melt anything. The Mk 3 versions are quite visible in full sun and a couple of guys wanted Mk 3 versions, however only one extra set was made. Apparently it was a nerve racking job and a problem with the CNC machine compounded the stress. I would like to thank Peter from the Trades Guild for undertaking this job twice. He won't be doing any more, he's off to his psychiatrist.
Regards Martin.
