Hi, I'm on the same journey now and defaulting to the RainExperts, but a little worried about reviews saying they are quite chunky/stiff. What did you end up going for? Richard

There's quite a lot written about the legality of LED H4 replacements. The classic car LEDs are stated as CE compliant, but I'm not sure how an LED H4 can be compliant, simply because the H in H4 stands for Halogen, so you're changing the technology out and there doesn't appear to be a way to test an LED version - the regs need to be updated. I might be worrying about nothing, but if someone complains/says they were dazzled and the lamp is checked and found to be non compliant, problems may be just around the corner. I've bought some H4 LEDs but am not sure about fitting them, and may just wait for a compliant unit to come available at a better price than currently - the official Caterham inners are £350 each from JAL.

You'll need to remove the: Wiring from the econoseal connector, if you're reusing the headlamp inners. If you're getting a new headlamp/lighting then snip the wires and then rewire the new. There should be a grommet where the wiring goes through the side skin which will stop the wiring pulling through. ARB brackets at the front by the radiator. You may need to move the radiator but check your particular car. Spring/damper, one end only. Jack the car up and pop it on axle stands, you can let the wheel drop, or support it a little. Front upper wishbone bolt. Then it's a case of wiring the headlight through the new bracket, best done off the car, and reversing the process...read some blogs about the wiring, it can be a pain but it just needs some time and some silicon lube to help it.
