LED bulb issue

I've recently replaced my rear licence plate bulb with an LED. Now whilst the looks have been improved 100 fold there is a bit of a problem.

When I brake the right indicator lights comes on ever so slightly, i.e. half lit, and when I actually turn the right indicator on it flashes twice as fast as normal.

I think it has something to do with the different current LEDs use that's spazzing the other bulbs out but any ideas how I go about curing the problem?

Turn signal issues with LED bulbs

LED brake/tail lamps will not flash with thermal flasher units due to their extremely low current draw. Also, with stock flasher units, the turn signals may flash faster than normal (Hyper-Flash). These installations will require an electronic flasher unit, available in our car bulb shopping category (for some vehicles) or at your auto parts store. Try to find flashers designed to work with LED bulbs, they will say "LED compatible". Often HEAVY DUTY flashers will also work with LED bulbs.
 
Ok, LEDs are a speciality of mine, I did my Uni Engineering report on ultra efficient, high output LEDs. Tell me what current is being supplied to the number plate light, ac or dc. Then we can go from there. What you want to end up with is a circuit that has an input and output no different to the original.
 
Rightio. How would I go about finding the ac or dc bit out?? I know absolutely nothing about electrics!! :s
 
well I'd imagine that it's still DC, since it's probably powered by the battery, unless there's a dc/ac converter in the system somewhere... anybody know???

But anyway, the bulb you took out, take it to a small independent electrical store and ask them what's the current drawn by the bulb. You can then match the LEDs you put in to the bulb you took out. Most bright LEDs operate at 350mA, I have no idea what the standard bulb uses. Once you've done that, you can then tell me the details of the LED bulb you're using and I'll tell you what components you need to fix the problem.
