Dave, found some on Rapid, which would you go for ?

I'd go for the 62-8112 (HS25 10R). That's a 25W 10 ohm resistor. you'll actually be dissipating 15W in a 10 ohm resistor, so that will be fine.

Maplin and RS also sell equivalents.

Well, the resistors turned up so I pop to do this lunch time.

A quick test and wow no bulb out ..

So Dave you were correct 10 Ohm resistors seem to do the job.

THEN DISASTER !!! OH no when I was putting the assembly back, fekr.gif

DON'T PANIC !!!!!!!!!!!!

How the hell am I going to get that out ..........

Did not take me more than 5 minutes, thank god ...

So the only thing to test, is to see how hot the resistor gets and to see if they will need bolting down.

Thanks for reading

led's are the best to go for without the need to change resistors and the like?.

With ALL LEDs you need a resistor to make them take the same current as a "normal" bulb to stop the bulb failure warning happening.

Until someone makes a LED with a built-in resistor you'll need external resistors like Andy.

....Amazingly informative thread, Andy - Excellent How-To +++

Reading through it there may be some TSNers who would be interested in the Hella universal round LED DRL units I've just fitted. I'm thinking of those guys who would swop their fogs for them (A4's, S3's etc).

Obviously yours look ace within the headlight unit. Mine are Xenon and therefore sealed.

I'm going to post something in General Cars but meanwhile here's a link to mine in the GTI forum :
