I took the plunge this weekend and changed the fogs into indicators, fairly painless only needed to cut two wires and join a couple and splash a bit of bulb paint on, then hey presto no more naff indicators in the bodywork, they now take pride of place were god intended them to be.
They are a perfect amber and certainly bright enough, I put the hazards on for a while to test the painted halogens and no problem, even if it were it would also be simple enough to revert back, but no need, I’ve been using them quite a bit since converting them and all is sweet.
