I've gone back to the car, popped in some 21W bulbs on the front and it works fine Sadly the 21W bulb is far to big to fit inside the front indicator housing. Looking on the internet I can't seem to find a small 21W bulb. So its either resistors or a different flasher / hazard relay.

At least you have sussed out why and learned a little in the process.
Possibly try out some large LED's and resistors but I think you will need something to increase the load as before.
Audi/VW fit 12v 6 watt halogen bulbs to sidelight and they are very bright.



Good luck.

Can't see anything in the IVA manual about brightness so I'm not sure if 10w bulbs would pass. I got them from CBS online and at the time were called "IVA OK" However they seem to have removed a lot of their IVA claims recently for products.

It looks just as cheap to buy some different indicators than it does to fit ballast resistors. Its not super urgent at the moment, at least the wiring and controls are working.

Those resistors would not be anywhere near big enough - they would be 1/2 watt at most and would burn up very quickly. You would not want to put a resistor in series, that would increase resistance and therefore decrease the load. Going the bigger bulb route is the way to go. If you can't get one big enough in the housing, install a second repeater on the side of your car or just have a second bulb in parallel hidden under the bonnet where it can't be seen. Another bulb in parallel with the existing bulb will add the extra load required.

Hiding bulbs behind the dash doesn't seem like a very elegant solution. People on Ebay sell 25W and 50W ballast resistors to help with relay loads when fitting LED bulbs. I'll either buy new indicators or fit a fixed rate flasher relay off another vehicle.

I have led indicators at the rear and got my resistors from svc, they are not like an ordinary resistor as in your pic they are also mounted on a small piece of aluminium to disipate the heat

I think they were about £8 each but i did buy all my lights in one go from them so i may have got them a little cheaper
