LED Headlights - Fault
Wotcha.

I have a pair of Halo style LED headlights. Can't remember the brand, as I bought them off a mate in France. Everything being totally 'chicken soup' of course.

One of the headlights has developed a fault, or at least that's what I'm trying to confirm.

When only on side lights, so just the Halo ring is showing, the driver's side unit seems to have a dimmer colour than the passenger side. To use household lighting vernacular, it looks like a warm-white rather than the expected bright-white.

When on full beam, the driver's side doesn't seem to function properly, in that the slight dimming of the halo and the introduction of the beam (the beam is partial, and not throwing the full amount of light), aren't the same as the proper functioning, passenger side unit.

Do we think this is a wiring/conection/feed issue, or a faulty unit issue? I am REALLY sh*t when it comes to electrics, so I'm not entirely sure how to test it. Does anyone have any ideas?

Hi,
Just swap the lights over. If the problem stays on the same side it is probably the wiring.
If the problem stays with the “ faulty “ light, it is the light.
Obviously more complicated if it turns out to be the wiring.
