Austin Champ LED lights
There have been a few articles on LED lights for classic vehicles. The advantages are: lower electrical consumption (helps old wiring); a much brigher light.
So I bought two LEDs for the sidelights and they are much brighter. The cost was £8.99 for two on eBay.
The second picture should have been taken at night but it still shows the difference with the old one. Next job is to investigate changing the rest of the lights.
