We'll see if it shoots sparks or not before too long, Rich.
This little light is a fender marker/turn signal by Lucas, used on Morgans and Rolls Royces from what I've seen. Apparently, the MG TD crowd can use them also. I want to use it as a third brake light, and asked TC offline if he still had his lens-coating recipie (which is why it now appears here in the 'Bugs' thread).
I will be frying another fish between now and when I install the light. It IS a Lucas, and it has had a significant negative impact on my car already -- and it was only SITTING on the tonneau when I took the picture! Maybe that was an omen?
I have two brake light switches in my master cylinder; one is a long-dead German one which has been plugging the forward outlet for a while, and the other is German also -- and died this morning. I believe the Prince of Darkness (Lucas) might have been responsible.
My spare brake light switch -- unused, kept in the tool bag for just such occasions -- is Chinese. I installed it today, only to find it DOA.
While re-wiring the entire brake circuit, I fried a fuse. I use the little ceramic guys everybody but me hates, since they're uber reliable and I can clearly see if they're blown or degraded, and usually keep a stockpile of spares in the toolbag as well ... But I took them out of the bag last week. Verdampt!
Wolfgang was on site for some of the effort today, and brought me a brake light switch from an old master cylinder he had lying around (shocking!), but it also failed to perform when installed. It was a long shot anyway; I think it came from a Beetle so old it was sold new with stone tires. Barney Rubble's old ride, maybe.
Nonetheless, I ordered a new German switch from a local parts place, and they said it would be in tomorrow. Hopefully, they'll have an 8-amp fuse or two there also.
Wolfgang, thanks for donating your afternoon to the cause. I used most of that yellow wire for the rear section, including the shorty going to the bulb. It's now brown-to-yellow, instead of brown-to-red, but it's consistent.
When this stops being fun, I'm buying a Miata -- but don't hold your breath. ;)
