Does your Twilight Sentinel (automatic headlights) work? I've actually only just noticed that, on my car, the headlights come on all the time, even in broad daylight. If I flick the lights off during the day, I get the 'Headlamps Suggested' message on the DIC. Wondering if this is a side-effect of DRL deletion on US imports?

Any feedback from others with US cars appreciated.

Cheers,
Ian.

Twilight Sentinel is working fine on my 2007 C6 import.

Works fine on mine too, although I did read somewhere (here?) that if the SVA mods are not done right that this doesn't work properly.

If your twilight sentinel operates I am guessing that you still have DRLs/orange marker lights during the day as you drive? If so, they're actually not legal. Disconnecting the twilight sentinel is the way to prevent the DRLs from operating and as a result the car will always think it is in ambient dark, hence the headlights coming on every time you start the car. If you turn them off you will get 'headlights suggested' and you can clear this straight off the DIC and it will not come back. Please correct me if this is different for any of you, but this is how we wire our conversions and we have spent a very long time refining our conversion.

Mitch, this is exactly how mine behaves. DRL not operating and headlights come on everytime the car is started, regardless of ambient light level. Slightly irritating that I have to flick the lights off and clear the 'HEADLIGHTS SUGGESTED' message everytime, but there you go. There must be a more elegant solution out there somewhere.

Cheers,
Ian.

Front orange DLRs are not illegal - they have them on all current BMWs. The issue with the C6 is how you handle the rear lights / indicators so they don't come on too.

Interesting as I don't have the DLR's on at all (front ones are now indicators) yet the lights don't come on automatically unless its dark, certainly not at start up unless its in the garage.

Hmm... can somebody clarify what the score is here?

Am I the 'victim' of a slightly less elegant SVA DRL deletion? What is involved in getting my Twilight Sentinel working as it should?

Cheers,
Ian.

I think that the solution is not the same for all C6's as my understanding is that there have been some changes throughout the production run but it's still not straightforward fuse removal as on the C5.

One alternative option is to have the light sensor connected and either leave the car on side lights (the dash will then just says headlights suggested when actually the case) or leave on auto and remember to turn off DLR by rotating the light switch back when you first start the car and pull off. It's best to add a DLR LED indicator so you remember.

Could you clarify which model of BMW now has orange DRL's in the U.K.?? I've never seen one. Volvo used to use DRL's and used the front sidelights, not ambers or indicators. I am pretty certain that this is illegal. Will confirm with my aftersales director though......

Discovery's have them. They are not illegal as long as you have a white light as well and they conform to the angles of visibility.

Official European cars don't have DRL and only suggest headlamps when it is getting dark.

Thinking about it though, orange sidelights/DRLs must be legal because the "side marker lamps" on Euro/UK cars are orange (although mine aren't anymore, at least when they're not lit! wink).

The current 5 series does at the top of the indicator - it can be disabled though by going to the options on the command screen

My TS works just fine on my C5 which is a US import. I inhibited DRLs by doing the jumper mod but it also worked fine pulling the A2 fuze. I suspect its a C6 thing.

C6's are a much harder car to do a light conversion on due to the current that ends up going through the brake lights. We have to create some resistance to stop the bulbs from blowing. There are however a number of ways of going about these things though....
