Overhead Courtesy Light Question

[FarmerPug]

Would it be possible to use the power coming from the courtesy light in the headling at the front to turn on and off a relay, and would i still get the nice dimming effect.
Is this free from bsi worries?

[FarmerPug]

theres just some questions that cant be awnsered, is this one of them?

Oh, er, sorry, I can answer this - no, you can't run a relay off a dimmer circuit. I guess it'll energise when the current is high enough but there's no way it'll dim the same as the courtesy lights. This is also run straight off the BSI so I wouldn't touch it.

[FarmerPug]

so the dimmer bit is from the bsi, but what about the power for the light when you set it to turn on with the doors, is that bsi controlled also, does the lights dim off when a door is closed? I tried buying the rs thing but they dont accept paypal.

[steve_earwig]

But it dims when you shut the doors.

didley squat dam, can d8 owners just wire up anything to their courtesy light since it doesnt have a bsi. But ill just buy this opto isolator from rs then, no other solutions?

Hi
Dunno if this helps cos im crap with electrics but i about 2 yrs ago fitted 2 more interior lights (same as headling ones) as footwell lights in front
-both are wired,ie tapped into, the front headling light and work exactly the same as the roof one dimming out is the same, and no fires yet!
btw its a 1999 d9 hdi not multiplexed at least not fully multiplexed but does have a bsi (Bull sh*t Inside)

[FarmerPug]

does pre multiplex d9s have bsi systems?

does pre multiplex d9s have bsi systems?

They sure do, mounted behind the fuse board inside made by siemens. i have replaced mine with a later one to enable cruise control on my 99 hdi.

hows it possible to wire extra lights without blowing it up then
