[Healeys] Lucas headlights

[varley at cosmos.net.au (Larry Varley)]

Something that I think seems to be missed here, is that a headlamp relay 
is generally a special relay with thermal overload rather than a fuse. 
Do you really want your headlights to decide to go off while driving at 
speed on a winding road? A proper headlamp relay will flash the 
headlights on and off if there is a problem in the wiring, as the 
thermal switch in the relay opens and closes contacts. Food for thought.
