Road-legal* Philips LED lights

TL;DR should pass the yearly inspection, better illumination than the proper LED units

The OEM H4 halogen lights are ok but not the best to drive at night.

After some research I came across the Philips Ultinon Pro6000 series of LED products. I got the H4-LED 5800k kit as well as the W5W T10 6000k kit for the side lights.

Removing the headlamps from the bowls is just a matter of removing the two bottom screws on each. The side near the car requires a very short thumb screwdriver, or have a philips bit fitted to a ratchet wrench. That or remove the nosecone altogether. Up to you.

(*) Road-legal, maybe, but actually not on the Caterham as the 5.75" lights with their specific E markings are not listed on the Philips documentation (yet).  On the other hand, any classic car with 7" beams like the classic Mini are ok and listed on the spec sheet.

But it looks great and works well. 

I've since upgraded to a full led kit similar to the one Caterham sells for a ton of cash, but the original headlights with the Philips Ultinon kit give a better illumination. They win on practicality.
