Dave, Speaking of cottage industries: do you recall a black box which when fitted into the lighting system could be switched to make brake and side lights much brighter, for use in fog, I fitted one on my MGB and as I recall the internals contained a ballast resistor, a bulb, and I think one had to replace the stop/tail light bulbs. Anyway, it worked really well. I have tried Googling (new verb for Websters) but without success. You seem to have a wealth of MGB knowledge. Meabh.
