Hi, just finish fitting and wiring 4 grab handles in the vito. 2 x rear wired from the interior light at the back, and the fronts, fitted both sides from the front interior light, all work as they should and fade out as they should, all good there. Question is the light is not clean and yellow so can I swap the festoon bulbs for LED. Will I need canbus ready type? Can I also fit them in the door lights? And lastly a recommended bulb. Just looking for a nice clean white/blue light.
