I bought these "off road" lights from Harbor Freight. They are 55W bulbs, but you can swap them out for 35w. I haven't installed them because I don't have a mount yet for them. I was going to use a flat piece of stock mounted into the existing light holes and mount the headlight and extra lights on it.
I'd think twice before quoting "35+35 = 70"
35 + 35 = 70 is most certainly correct only if we look at power consumption.
However, if we look at "
illumination " then I'm afraid it's a totally different business.
I'd consider using square root of two, or even sq.rt. three, to calculate illumination at increasing distances.
35+35 => 50ish, or even 45ish as distance increases...
So, my suggestion would be to use two 50-55W lamps, and possibly alternate the center headlight with the two extra ones, by using a "commuting relay" switch, i.e. a relay that switches between two loads, rather than switching the load on/off.
