Yeah i've got one in the front and one in the rear too,

Front one was a 6 led festoon bulb from here (3rd row down), you need to know the size first, then click white at the top and choose one of the cool white ones. They are FUCKING BRIGHT though, maybe i should have gone for the 3 led one!

The front and the rear bulbs in my car are different lengths though for some reason, i bought 2 shorter ones thinking they would be the same but the rear takes a longer one!

So could be an idea to whip them out and measure what you've got in there first!
