en eftir að ég setti það í kemur í mælaborðinu : Low beam : Lic plate light : Brake Light : en öll þessi ljós virka,

er búin að reyna að googla eitthvað um þetta en fynn ekkert

veit einhver hvað gæti verið að ??

væri þá ekki allveg eins hægt að tengja checkið fyrir low beam inná rásina fyrir háuljósin, þannig að það tékki bara á þeim perum

ELIMINATING THE "LOW BEAM" MESSAGE ON THE OBC

If you were to decide to drive with your HIDs on at all times, switching on your low beams before even turning the key to the on position, you would never have to see the "low beam" message. However, this is not reasonable, and something has to be done to eliminate the "low beam" message when you are not using the headlights. The HID low beams have no filament, so the system will always think the bulbs are burned out when the HIDs are not turned on, so how do we fix this problem?

The solution is to trick the LKM / OBC by making the system check the high beam bulbs (normal halogens with filaments) while it thinks it is checking the low beams. The high beams are normal halogen bulbs with filaments to complete the circuit the system is checking for, and perhaps with the correct resistance in case the system is also looking for that.

The solution is simple, yet brilliant. Garrick Louie came up with it and shared it with me, and I am very grateful to him for this. The solution involves using a 12 Volt N/C (normally closed) relay, wired such that when the lights are turned off, the low beam + lead is shorted to the high beam + lead through the N/C circuit of the relay. Therefore, when the lights are off, the LKM/OBC will find the connection (and perhaps resistance) it is looking for via the high beam halogen filament. Remember that the HID has no filament, so when it is not on, the + lead going to the HID bulb is effectively disconnected.

When the lights are switched on, the 12 volt current passing through the low beam lead triggers the relay to switch to the OPEN position, breaking the connection to the + lead of the high beam so that they LKM / OBC system can only "see" the low beam. Simultaneously, the HID bulbs fire up, so that system recognizes a complete circuit on the low beams.

You will need to replace the fuses for the both of low beam bulbs (one fuse for each low beam) in your fuse box. The standard fuse is a 7.5 amp, but I changed them to 15 amp with original BMW fuses from the dealer.
