The bulbs I purchased came from China Aliexpress & cost pennies - if you want to be a little different you can get orange, red, green, blue etc. for the interiour, im thinking of getting red / orange as it helps with night vision.
Side lights on many cars are w5w bulbs and you can get some nice bright 2- 5 watt LEDs for that DRL look, just don't choose to high a temperature as they will look blue. 4,000k is about right if u want bright white, 6,000k is starting to turn blue.
I could go on about fog / head lights, but u have to be very careful on what you purchase, as a lot of these lights need lenses to stop u blinding the drivers coming down the road towards you!!! I think most of us have seen the dazzling bright lights fitted to old cars, the light just scatters all over the place and is very ineffective when night driving as the light pattern cast on the road is usually very poor.
A common Brake light is a 21w bulb, so again if you want that led look, you could start here http://www.aliexpress.com/af/21w-led.ht ... xt=21w+led
Just make sure you check the bulbs type / colour in your car before you purchase. Some bulbs are coloured, some not, so take a look at yours first.

That's what the resistors do - fool a standard flasher relay into thinking the LEDs have the same resistance as ordinary bulbs. Unfortunately that means there's little power saving because the resistors draw power to simulate load and "waste" it in heat. If Daewar's LED bulbs flash normally that suggests that the relay is LED-compatible and no resistors are needed. I'm sure he'll tell us!
