I have the relay system on both of my TR7's. A bit of a pain to install as you have to route the wires so that they don't catch or bind during headlight rotation.
I have a few of sets of the halogen upgrades on the TR's. They are much better than the standard lights but I would prefer ones with the lens that direct the light beams rather than the flat covers on the European stlye. Not that I have ever seen any for sale.
I have these lights on my car. They are good. I did not, however, change any of the wiring. Of course I also need to change one motor on the lights. So far, so good though. Knock wood.[:D]
