Headlight relay for land rover discovery 1

PAWEL IS A BOT. HE POSTS GENERIC ANSWERS. AND OVERLAYS NAME OF YOUR CAR. 82 GENRIC ANSWERS HIM
AND LIES ABOUT IGN SWITCH.
NOW YOUR CAR.! FACTS, ONLY, 1 CAR
LEARN TO USE THE DMM , CORRECTLY;
HEAD LAMPS ON.(SWITCH) NO KEY IS NEEDED FOR HL.
IS DRIVER LEFT OR RIGHT,? IN USA LEFT.
IS HIGH AND LOW BEAMS DEAD LEFT? No TOLD AT ALL.
PUT METER BLACK LEAD TO THE BATTERY NEG LUG
THEN PROBE RED TO ALL WIRES OF DEAD LAMP 1 BY 1.
12VDC IS GOOD 0 BAD
IF LAMP GROUND PIN READS 12VDC <<< GROUND FAILS.

LEFT LAMP USES GROUND LUG G101. IF R

CAR HAS DRL. SO DRL AND MANUAL LAMPS FAIL
HIGH , LOW , AND FLASH HIGH>? NOT TOLD
DOES ENGINE RUN? OMG NOT TOLD.
THIS CAR RUN HL RELAYS BY BCM CONTROLLER BRAIN


FUSE ARE ON THE OUTPUT OF ALL HL RELAYS
SO IF ALL FUSES INPUT(TOP) ARE DEAD,THAT MEANS
BCM IS FAILING. OR THE SWITCH TO IT.
OR FUSES BLOW TO BCM
WE SCAN THE PCM/BCM TO SE WHY.


HEAD LAMPS ON THE 4 FUSES ALL 4 RIGHT SIDE ARE
12VDC, IF NOT BCM IS MESSED UP, OR RELAY DEAD.
HE LOW BEAM RELAY RUNS BOTH SIDE
SAME WITH BEAM. A RELAY FOR IT.
DRL HOT ONLY IN DRL MODE.
DRL; HAS A SUN SENSOR (AUTO MODE)


BOTTOM HERE IS HEAD LAMPS.SIDE.

HEAD LAMPS ON USA WORK EVEN KEYOFF
SO DOES BCM TO DO THAT, MAIN BATTERY NOT DEAD

Check that your fuses and bulbs are still fine

Could be that the low beam relay is stuck. If you can locate the relay usually in a fuse box in engine compartment ,remove it and see if lights go out.

The main beam isn't designed to "dip" to oncoming traffic. When you "dip" the beams, it's the high beam that drops out until you click it back to high again. If you have the optional automatic vehicle approach system (NOT just auto headlights) the high beams will dip automatically to oncoming traffic and then go back to high beam again after the oncoming traffic passes.

The headlamp circuit is rather simple. From the 15 amp RH headlamp fuse, there is a red w/yellow trace that goes to the RH high beam. Out of the 15 amp LH headlamp fuse, the wire going to the LH Hi beam is solid red. Both of these wires should have power when the headlamp relay is energized. The wires from the Hi Beam bulbs going back to the switch should both be red w/black trace. The wire going from the headlamp relay to power the 2 15 amp fuses is white. The headlamp switch applies a ground to illuminate either the Lo Beams or the Hi Beams.

call or text 7328568836 and i will walk u through it

good day, its either you have a high beam relay problems or a faulty bulbs that needs to be replaced, have it checked. hope this helps, have a nice day

it should be located on the fuel line around the middle of the car if not its about 2 1/4 inches by 4 1/4inches

I would start at the fuse or relay, typically there is a separate fuse/relay for low and high beams. If that checks out I would look at the light switch, also check to see that there is power at the socket and that the lights are properly grounded.
