Lights issue - Fixed.

[AlastairA]

Hi,

Building a 420R at the moment and have wired in the lights (LED version). One of the lights is working just fine, the other has an issue with the daytime running light (side light) not working. Wondering if anyone has a wiring diagram or knows the wiring configuration of the lights?

Many thanks,

Alastair

Email sent.

Is this all within the headlight bowl?

Do you have a multimeter?

Have you swapped the headlights over?  

That would determine whether the issue is with light (if problem also swapped) or the wiring (if same as before)

From my 2013 Assembly Guide:

LED lights are polarity sensitive. Have you checked the polarity of the supply ?

Hi All,

Many thanks indeed for all your helpful comments. The issue was with a headlight assembly that arrived from Caterham with a piece of masking tape across the front marked "Wrong Lense" - so I was quite concerned.

With the help of the wiring information above, I found that no power was getting to the LED assembly on the Red wire (sidelight). The red and black cables had spade connections halfway along the length, but were wrapped in insulation tape rather then heatshrink (which was evident in the other headlight). On removing the insulation tape I found a rather bodged crimp on the spade connector. Restoring that connection fixed the issue.

Many thanks again!

Well done. And thanks for adding the solution.
