Hi,
Even now, its a very pleasurable county, even when under h2o? I went for the white bulb. My only cause was that I assumed it would be brighter particularly for the brake light-weight ( underneath the crimson lens protect ) and also supply better illumination of the quantity plate.
Low cost as chips on flea bay. I would just look at polarity, and voltages when purchasing. Stick to one which is for 6 volts only and stay away from 6v – 24 v variants. Far too dim at 6 volts.
