middle interior bulb to led

[maxthecaddy]

change the caddy cabin interior middle bulb today to a led one and noticed it stays on very dim, open the doors light comes on shut the door light goes off but stays on very dim any one had this problem

Did a search and found this

Then changed the interior bulds for LED.... i found with these they didn't turn fully off when the ignition was on but did when the van was locked, bit of research i found there are small leakage currents that are not enough to light a standard bulb bit will keep the LED on in a dim state, this is fixed by putting a load resistor in parallel with one of the bulb, so i soldered a 1k ohm 0.5w resistor to one of the bulb and all work well now”

O just get a decent bulbs. I have Osram led bulbs and they don't do that.

I got mine of the bay from a seller with good feedback and they worked too.

thank you for this search you did for me, might come in handy

The bulbs I got are also for number plate lights so have a resistor built in so as not to cause errors threw canbus

Mine do this, they are spotlights mind you, planning on changing them soon.

yeah mine have the resistors in them but still stay dim, but thay was the cheap ones i put in

You might find a resistor used for error canceling is not ideal for this. Their residence will be quite high in comparison to the LED so in current flow terms there will be little or no effect.
Try a filament lamp in parallel with the LED, that should soak up the leakage current sufficiently to stop the LED illuminating to a visible level while not causing excessive heat.

THANKS DOC it works and no cost, best free info

Nice one, I'm glad I could be of assistance.
