Nothing wrong with laning at night, there should be no lane that can't be driven without due care and attention at night. As for lights a long beam is very handy when laning, it gives you a good view of the road ahead and the correct lights will give you a good close in spread of light. Agree with the high mounting an stepping back though
To the OP, mine are roof mounted at the front and sit lower than the rear roof, I will put up a pick tomorrow. The lights have heavy duty fully waterproof casing and being LED they produce minimal heat which stops the lenses cracking as well as being low power, I looked at lots of options and decided that its worth the extra money!
