ross501:
just been brought a light bar  for the discovery and was wondering how people wire them e.g all on just 2 and how do people get cables to them without having a snorkel  and has anyone got any ideas how to get them to come on at half power so they can be on all the rime

SWEETY:
Just made one for my D2 & will be wiring it up soon (waiting for the cable to come)I'm going to run just one cable (20A) up to power all 4 spotlights (55W) The cable will be routed around the gutter by the windscreen & underneath it to come in via the drivers door seal where it'll go down behind the A post trim under the dash so apart from about an inch of cable the rest will be hidden on the inside

4x55w spots will pull 18.3 amps. No much leeway in a 20 amp cable?

amps=watts/volts

Disco Matt:
IIRC having them on at half power constantly is illegal?

Mine are wired to come on with full beam, but via a switch so I can either have normal full beam or full beam plus spots. I just took the wire up inside the A pillar and then out via a hole in the roof - sealed it with a plain rubber grommet and it hasn't leaked yet.

Saffy:
Switch in 1ohm high wattage alloy clad resistors per pair lamps like the dim/dip resistors used on certain landrover models.
