Hi all need some help again and it involves my worst topic those wires ! I have recently purchased a GBS zero 2017 build and a Mazda MX5 base it has halogen headlights and LED side lights in the same unit, side lights are on all the time and only one headlight works I have changed the bulb to no avail can anyone tell me where to look next and if sidelights perm on is normal and indicative of a fault ?

Fuse box would be my next check. A lot of cars have 4 fuses for the headlights Left Main, Left Dip, Right Main & Right Dip.

If you do not know which fuse systematicaly remove one at a time to check if blown put good fuse back and check the next one.

I sometimes feel this sub-forum is pointless for kits 😀  - most kits have a completely unique electrical system and it's almost impossible to help remotely. My wiring loom is half of the GBS system and half my own design - no-one is going to work it out 😀

Having said that, a halogen and LED in the same unit? Don't LEDs use a lower voltage, so they should be on separate circuits? Also, LEDs are polarity sensitive- maybe 12v in the wrong polarity is keeping the LEDs on and preventing the halogen coming on? Dunno, I would get a multimeter on the wires and see what voltages you're getting...
