Popped down to the garage to see the car today. Went to swap the clocks, as I had swapped the ones from tubs when I thought I could swap the reg across. Swapped all the red bulbs from the clocks while I was on.
Tried to test them before everything was back in place, but they weren't working for some reason... Spent ages checking connections, then gave up and put everything back... Was only when I came to put the switches back and reconnected the dash dimmer switch that I remembered that they don't work when that switch isn't in. I'm sure that I had the same problem all those years ago when I first put the red bulbs in.
Felt good sitting there with the engine running
After New year, it'll be skirts on (they're looking good all painted up now), mot, then back to me
