tf lights staying on
 
just went round to the shop and my daughter noticed that the map lights in my tf mirror are staying on,but staying very dim,is it because they are led lights,could this be a problem with draining the battery,could this be the problem when my alarm kept going off,anybody had any similar problems?

I think that has something to do with using leds, have you tried normal bulbs to see if they're the same

dont they need a resistor in the line, to close them down.

I know nothing about electrics, just something I've read somewhere!!!!

Just because they are led's Andy. Takes so little to light up an led. When I had all rear lights as led's my high level brake light lit up dimly. Nothing to worry about though :)

As above, had the same in my last ZS. Use CANBUS friendly LEDs and it should stop.

I have had this discusion on several of the F/TF forums - map lights fitted with LED's in the F/TF do not normally stay on.

I'd remove the LED's and see if that cures the alarm problem.

Remeber they are not staying on but are dimply lit...but if not then I would suggest a difference between f/tf's and zs's then as all three of my zs's have had this. On ZS's if you have no tf mirror and fit an led festoon into the standard interior light you get a small glow from it but if you fit a tf mirror with led's then the glow appears in them instead...would guess this is due to the fact the wiring is spliced into before the standard light.
Not just cars, I have led replacements for halogen bulbs in the house and they pick up residual power in the wiring and some of the individual leds glow slightly even when the switch is off.

What I am saying is that a illuminated mirror in a TF with LED bulbs should not have even a residual glow, the system that switches these lights on is wired differently to in the ZS.
The power is controlled by on/off switches, not an electronic control board.

Yes but as most leave the switches in the on position so that the lights come on with the interior light then there will be a glow.

But hay ho, what do I know.

Wind and pish apparently.
