Replacement LED front indicator units
As well as the rear LED bulb upgrade to Cree LEDs, I've also replaced the front indicator units with sealed LED units. They are made by WIPAC and are E-marked and DOT-marked so should be compliant in many countries, including the UK. If anyone wants to know exactly what markings are on them just ask and I will post them all and take a picture. Plenty of info on the websites selling them too - see below.
Fitting
These are 73mm outer diameter, which is the same as the originals that they replace. They are mounted on the original pod but you need to drill two new holes as the mount holes are different. I bought some M4x40mm pan head machine screws and nyloc nuts in stainless steel to mount them through the pods. The wires were supplied with an AMP-style connector and a wire length of about six inches, which is not long enough for a Caterham. So, I bought a couple of sets of AMP Superseal connectors, which are waterproof, and snipped the wires at the back of the old indicator units and crimped the connectors onto the original wiring so that they are hidden under the indicator pod and cable-tied into place to keep it neat. Saved having to push new wires through the headlight mounting tubes etc, but you do need to sacrifice your old units by cutting the wires. Happy to post pics if anyone is interested.
Performance
I've done a side-by-side comparison with my old indicator units with clear lenses and "standard" amber LED bulbs that have three LEDs pointing forwards, the rest around the sides. The new unit is on the left in the photos, shown both illuminated and off so you can see how they look. The peripheral performance is limited (i.e. viewing from an angle other then straight ahead), but owing to the fact that there are 16 LEDs all pointing forwards, when you are in front of them they are almost blinding!

Cost
These are being sold to both Land Rover Defender and Harley Davidson owners on lots of websites. I bought mine from here and paid about £35 including postage for the pair. A search for wipac led clear indicator should give plenty of options. A bag of 5 sets of Superseal connectors is about £7 on ebay and a crimping tool can be had for about £15 if you don't have one. I bought a cheapie and butchered it to get it to work - fine for a few pins like this.
This is by far the best lighting upgrade I've done to my Caterham and will hopefully give me a chance of actually informing other road users what I'm about to do
Apologies if someone else has already covered these units but I couldn't find reference.
Cheers,
Andy
