Check out ebay.
I just did a simple search and it turned up 5000+ hits for driving lights!
ie. 150 watt 8 inch round driving beam lamps.

Hamsar lamps. These are really good. they are Hella lighting but less exspensive.

I my self have and will be using two 8 inch round pencil beam lamps and
two 6X9 inch rectangular Dick Cepek driving beam lamps up top the roof.
With a wired remote operated search light in the centre of my light bar.
Also, as TBJ pointed out, beam pattern is the really important part of the lamp.
You have pencil beam, driving beam which projects the light pattern far and wide, but not as far as a pencil beam lamp.
Then there are wide angle lamps, fog lamps which of course have a sharp horizontal light beam cut off.
If you have any more question, feel free to pm me.
Cheers

Thanks for the replies. I have already looked at KC' s & Hella 's. I am going for intensity/distance not pattern. HID are too expensive. I would like to be able to photograph winter, mountain roadways ahead scenes, with wildlife etc. The basic 55's are not bright enough and do not allow the best exposures. The brighter the better. May start searching for search lights etc..that may fit the bill.
Yes, but the fluting on the lens or built into the lamps reflectors are what create the intensity and distance! Not just the wattage of the bulb!
So the
pattern is very important. Look at the four Bosch 225 lamps on the front of my Mini in my avatar. With those four lamps and my two headlamps, I have 960 watts of light. But if that same wattage was in cheap ass lamps, the intensity and distance would be nowhere the same. A cheap lamp scatters the light and causes stray light to get projected where you don't want it and the lamps then are inefficient!
Also, search lights tend to either have an adjustable beam pattern or a fine focused spot or pencil beam/pattern and then you have a to intense hot spot!
