Number Plate Lights 451
The new smart fortwo has better licence plate bulb holders, these don't break as soon as you touch them like on the previous model. Here is how to remove them to change the bulb.
Removing The Bulb
Slide the unit over to the right and pull down.
The unit should swing down very easily.
The other end can now be pulled out.
Both connections can now be removed and the bulb swung out from the left.
Replacing The Bulb
What you require is a 39mm long festoon bulb.
You could also consider replacing with an LED festoon bulb, they give a better light although cheap ones rarely last long and they have to be put in around the right way or they will not illuminate. If this is the case, remove the bulb, turn it around and refit.
