Replaced my sidelights with LED lamps.
I note, when the ignition is turned off, the LEDs seem to go to half power & stay on for a minute or so - which I understand is how the car's system works (interior lights, window switch lights etc all stay on for the same time).

However. At work the other evening, I had to bring 2 buses into the depot(they have to be parked in a certain way for them all to fit).
1 bus parked just by the door to the depot, the other parked across the yard by my car (even my fob doesn't reach the car). when I blipped the fob to open the bus, I noticed my LEDs flashed Putting it down to a trick of the light (maybe a reflection off the bus' lights as they flashed), I put the bus away.
Came out to get the second bus, blipped the fob & noticed, again, that my LEDs flashed. Blipped the fob a couple more times to duplicate this event & sure enough, my LEDs flashed each time.
I've since noticed that they do the same thing in Tesco car park when others lock/unlock their cars.

Strange thing is, I never noticed this with the tungsten sidelights.
What is it about my car's system / LEDs?

Fascinating - and no idea I'm afraid.

Hi Sludge,

The only thing I can think of is that led's operate at far lower power than filament bulbs, when the electronics were designed this was not a problem.

Could always get a voltmeter on it / put back the original bulbs see if it still happens. All cars must be listening for these signals all the time they just only respond to their codes.

Cheers, John

Interesting theory. I suppose all cars have to react to any signal on the correct frequency in order for them to process the info & open the car etc.

I wonder if it screws with other people's minds when my lights flash in response to their 'blipper'
