I thought I'd upgrade the lights in my gq so i had more than 4 candle power and I didnt want to go down the HID path. I didnt look too hard but the only sealed ones i could find were basically the same brightness as stock factory and i really wanted something brighter so i went for semi sealed with nice bright globes.... First trip out and i had muddy water in one. They leak like a sieve and once the reflector was dulled by dirt plus the condensation on the inside blocking the light, then my new brighter globes were hardly any better than the old dull ones.
As i dont drive much on highways or on open flats i dont think ill ever go for a HID conversion but instead opt for a led light bar in the future.
