To the OP, when your bulb was working, how bright was your gear indicator window? Reason I ask, I just went thru replacing my TS switch, bought a new gear indicator assembly, and the illumination that I get is horrible, as in pretty much nothing. My bulb is lit, but it gives like zero light to the gear indicator. If it is really dark outside, I can just barely see a tiny glow on the gear indicator needle. And I mean barely! Hacks me off every time, I put in a lot of electrical work and gear indicator illumination is awful!!!
