While bulb replacement can help, you often end up with just minor improvement.
One thing that can help is adding auxiliary lights to the front of your motor home. I added a pair of PIAA lights to my Jeep and they can turn night into day. If you are travelling with other motorists, you must
use them in 'low beam' mode, and with a touch of the switch, (no other motorists around) they go the 'high beam' mode.
The PIAA's are so bright, that when I pass the occasional street light, the light sensitive street lights shut off as they think the sun is coming up.
I am very
careful of when I use the high beam and anyone thinking about purchasing these should do the same.
Hope this helps.....................Rob
