All depends how much you want to spend, Cibie and Hella make great lights PIAA's are probably better still and light force by all accounts are fantastic. Personally I've got a mix of Hella 2000s and Cibie Oscar+s and Turinis. I've done many years of road rallying (in the dark) and decent lights cost, they also last longer, don't rust have toughened lenses etc For once bigger does mean better (to a point) larger reflectors are better and more efficient than small ones but design still matters. You don't see many rally cars running round with Wipac or Ring lights on - they'll do the job but it all depends how much you're willing to spend and what you want of em.
