Lighting combos: headlights, ambient light and reading lights

The collection has many combos for lighting: they switch the headlights depending on the gear or rain, match the ambient lighting to the time of day and turn on interior lights when you get in and out. Here's what's available, which ones get in each other's way and what to check before using them.

Updated: 29 October 2026

Lighting combos can overwrite settings and, in the worst case, switch the lights off at night. Test every new lighting combo while parked and at dusk before you rely on it. Where the rules require dipped headlights, for example in rain or in tunnels, you are responsible for this yourself.

Headlights by gear and situation

The largest group are combos that switch the exterior lights by gear, seat occupancy or seat belt. They are all in the conflict group “Lights by gear and parking lights” because they can give contradictory lighting commands – use only one:

8205 0005 controls the lights by gear: parking lights in D or R during the day, dipped beam in the dark, off in P.
0145 0048 switches on the dipped beam when you select D or R or the wipers are on Auto.
8913 0016 sets the lights by gear and by whether the seats are occupied.
5442 0009 switches on the dipped beam as soon as the driver gets in.
5752 0024 and 3533 0054 switch to parking lights in P when someone is in the driver's seat but not buckled up; with 5752 0024, the automatic lights take over again when you drive off.
9538 0021 sets parking lights in P in the dark with the driver inside, 3734 0039 switches from dipped beam to parking lights in P.
4804 0027 only switches on the parking lights when you open the car and get in in the dark, 4470 0020 only the parking lights when you get in in P.

If you often wait in the car, the parking-light variants for P suit you. If the lights mainly need to be right while driving, go for 8205 0005 or 0145 0048.

Dipped beam in the rain

3383 0007 switches on the dipped beam during the day when it's raining and the wipers are on Auto; it was built for the G9. 9797 0017 reacts as soon as the wipers are on Auto, Lo or Hi. Both form the group “Rain lights” – use only one. 0145 0048 from the group above also reacts to the wipers and therefore overlaps with both.

Ambient lighting by time of day

Several combos switch the ambient lighting off during the day and on when it's dark. They differ in when and how they switch:

2941 0018: off during the day, on at night.
2607 0046: off as soon as it's light – it follows daylight, not the clock.
3997 0009: switches to match the time of day when a door opens; lighting settings may be lost.
1783 0050 and 7821 0004: off during the day, on after dark, brightness adjustable; 1783 0050 was made on a G6.
9875 0036: white ambient lighting when the car is in P in the dark – so you can see more when getting in and out.
8393 0055: colour changes in orange and red; you adjust the colours in the app.

They are all in the group “Ambient lighting” and can overwrite your own colour and brightness settings. Keep only one.

Reading lights when getting in and out

Reading-light combos are not in any conflict group, but some are meant as a pair:

6247 0056 switches on the driver's reading light when the driver's door opens, 9343 0056 when you select P. 8382 0044 switches it off again when you select D or R.
3764 0059 switches on the reading lights after you get in in the dark, until you select a gear.
8144 0020 switches on the reading lights when the driver or front passenger unbuckles – so nothing gets left behind when you get out in the dark.
6827 0041 switches on the rear reading lights when a rear door opens and leaves them on until you drive off.

Lights off when a door opens

The group “Lights and climate off when a door opens” switches off the headlights and air conditioning when a door opens – intended for short stops. 8223 0006 only reacts to the front doors and switches back on when you buckle up; 6322 0009, 9015 0005 and 1447 0005 are identical variants that also use the air conditioning's energy-saving mode. Use only one combo from this group, and remember that the headlights go off too, for example when you stop at the roadside in the dark.

A ready-made selection

You'll find a conflict-free selection from these groups in the set “Darkness & rain”. Reading lights for the back seat are also in the set “Family & kids”, and reading lights when getting out in the set “Getting in & out”.

What to watch out for

Keep only one combo from each lighting group; 0145 0048 also overlaps with the rain-light combos.
Test new lighting combos while parked and at dusk.
Before using an ambient-lighting combo, note your colour and brightness settings so you can restore them.
The guide “Combining combos: how to avoid conflicts” explains how conflict groups work.
