Were you the guy asking on Facebook? It's pretty simple, get any 21/5 watt bulb holder (often found in brake+tail lights, I go for N15 almeras usually) and wire it up so the 21 watt filament goes to the indicator and the 5 is spliced to the side lights. 4 joints each side, and maybe some jiggling with getting the bulb holder into the light unit
