Had an unusual one tonight! Bought a couple of led bulbs for the number plate light on the omega and the wifes vectra B as they'd both gone so thought id upgrade. Tried fitting them on the veccy and it wouldnt work. Thought there might be an issue with the holder so checked for power which was ok. Tried a normal bulb and it worked fine. Tried the LED bulb both ways round still nothing. Powered the holder direct onto the battery and it lit up fine. Thought i'd then try the omega and the same problem so again put a normal bulb in and all lit ok!! Puzzled I thought i'd see if anyone has any idea???

Probably wants a loading resistor, and if the car has CANBUS then you will need to buy the CANBUS version of the LED.
-
My rear number plate has an led bulb. Works fine but the beam shines straight at the floor and only illuminates a few letters/numbers
-
Martian is right on, but the light from an led is directional and has only a limited angle of illumination. If the plate is not fully readable at night then the bobbys may wrell give you a tug when you dont need it. :D
-
Bugger! I just got one for mine but not fitted it yet!!!!
-
If you twist the bulb a bit more towards the boot & they light the plate up no probs

To avoid the directional problem with LEDs all you need to do is sand them to create a diffused light which solves the problem. I've always done this with LEDs especially when fitting into your dash as it avoids the pinpointed light effect. ;)
Seems a little odd to me that they wont light at all even when im getting a 12volt supply into the bulb holder. I know what your saying about the canbus system but i wouldnt have expected that to have any effect on the light actually working?? i've got a resisitor i can try will put that in and report back. :y

OK if you say so.......still in the dark ages are we? :D

Just to check, have you tried it without the cover on? Depending on the size of the bulb it can be pushed back and break the contact when it's all fitted.

Not with incandescent bulbs, they appear to work as designed ..... unlike your LED's ..... :) :)

Congrats there Entwood you completely missed the cheesy sarcasm of my comment lol.

The lamp failure warning system expects to see a specific load in order to work

You can't use any old resistor, you have to use one that will produce the same load as the standard lamp you are replacing.
You also need to make sure it is man enough for the job as well, because if you use one that is under-rated for the job then it will melt in seconds.

Number plate lamp is NOT on the lamp check ;) ;)

It gets it's feed from the sidelight circuit which is fed via the lamp failure warning system, and by reducing the expected load the system expects to see it then fails to illuminate the lamp.

Doesn't really ;) .............. 1500 - 1530 in the Haynes
hence why a duff number plate lamp(s) doesn't trigger the lamp check :y
-
Don't have a Haynes in front of me Andy, but the wiring digram I'm looking at shows the number plate illumination is fed from the RH sidelight feed which in turn comes from the headlight switch.
Dunno why I read it as being fed from the lamp failure warning module, a second look shows that is connected across the lamp being monitored.......maybe it's time to upgrade the reading specs to 1.5x :(
@ PhilCav,
In your original post you said you tried the LED lamp "both ways around".....you can only put the lamp in one way so I'm a bit confused there.
-
ummm arent the numberplate lights festoon style martian :y so will go either way round :y

They come in two different lengths, and the difference is less than a handful of millimetres.
