You'll laugh athol35 when I tell you what the problem was in the end.
We checked all the wiring, relays, connections and the earth wires. And it all seemed ok.
We took the bulbs out and cleaned the contacts, but the problem was still there.
My mate thought we try some other bulbs. On placing them in we found that the lights were alot brighter.
So we checked the bulbs and found that the ones in the car were 24v when they should have been 12v.
So after all that it came down to the wrong voltage bulbs being in.
I felt like such an idiot
So thankyou for trying to help me out with my problem.
Now my car is back on the road
