New Bulbs

[TATO]

Hi everybody,
I'm trying to replace the bulbs in my 230 sl, because I live in Argentina it's hard to find 18W bulbs like the ones in the tail lights (stop light), is there any problem replacing these for 21W, should be any electrical problem with the car instalation?
Thanks

The difference being 3 watts is nothing to be concerned with. As long as the bulbs are the same dimensions since longer bulbs can cause issues with melting the lens.
