Have you got a link for the LED's you fitted to the interior lights?

I used these, they're only cheepo's but all are still ok !

Here you go Alan, very easy to install, just take note that they are LED's and only work installed the correct way round. There are other options cheaper or more expensive but i chose these.

Cheers Dan

Yeah most of my LED's came from these guys and they're okay for the price.
The only ones I had an issue with where the H3's and H1's. The H3's were too large to fit through the fog light mounting holes and the H1's, although they look really bright when you're looking at them, they produce a very poor light pattern, but they were okay about it just give me a refund.

LEDs on A/C Heater controls, Rear Evaporator and extension tubes, radiator, condenser, compressor, receiver/dryer, water pump (2x), steering rack with tie-rod ends, anti-roll bar bushings on front, belt tensioner, fuel pump and filter (2x), alternator (2x), heater return pipe and hoses (along back side of engine below exhaust manifold), heater outlet hose to rear heater plumbing with variable restrictor. A lot of this in the last year. With 220K miles stuff is starting to show its age. Hope to get another 100K miles out of it. Still drives great. Will replace the MAP sensor and solenoid pack this weekend.
