"Do you happen to know a source for the small circular lights?" A lot of British sports cars used stand alone warning lights. I saved the turn signal and high beam lights from a Sunbeam Alpine which was being scrapped. They have the interesting feature of flipable lenses--thick section for nightime--thinner for daytime. Old Saab 93&95 models (c. 60's, 70's) also used the round chrome bezel deep dish warning lights---and the tach from the 4 cyl models has red and green highlights similiar to the Volvo Rallye dash. -- Dave
