New head lights

(1/2) > >>

Hi all

I just installed a set of new headlight. The standard low beam lights are not sealed and just have regular globes.

The high beam are 100 watt "landing lights"

When I tested them last night, the low beam works perfect.
When I click on high beam, they are nice and bright.
After about 10 seconds on high beam, all the lights start to flicker on and off, so I go back to low beam.
Do you think this would be an easy fix or do I call an auto electrcician.

Thanks
Dan

Hi Dan

Not sure if all C3's but at least early ones have the lights wired directly through the dash light switch and harness.

This means you get a fair loss between battery and lights.

You may find your 100w lights are overloading the switch.

It seems common to turn the existing circuit into just a switch for relays that in turn enable the lights.

That way you get full power and no chance of burning out the wiring or switch.

Covered some of it here.

Look at using a relay in both high and low beam
To lower the curren draw througt the original wiring system
Buy quality relays  cheap ones will only give you problems
Re wire the lights to the relays with 4 sq and you will have no problems
If you pick up supply direct from the battery make sure you fit a fuse at least
Preferably a circuit breaker and a fuse

There's a circuit breaker in the headlight switch, sounds like it's tripping out or the "high low switch" can't handle the current.
As above, all you need a relay for the high beam (at least), so might as well do both.
Here's a diagram.

Easy job for a sparky

That is so much easier that trying to explain it is writing

I run supply to two breakers
one each for low and high beam
If there is ever a problem at night, you are reasonably sure that one beam will keep working in an emergency
