Not sure about the woodworking guy. But I would start by looking under Cabinet maker or something similar in the yellow pages.
Your turn signal/running light problem sounds like the wrong bulb. I’ve never had a problem…and my Duchess has been on the road for 24 years. It does not sound like a wiring problem. I’ll check the bulb number…but think it’s a standard yellow dual filament bulb. #1157 I think.
