I had this discussion just on the weekend. Horses for courses, its a balance of bling, budgets, and functionality.
I am happy with two cheapo Narva broad beams to light up 100m in front of me either doing tracks or highway. I don't care if a tree, mud, or rocks take them out, or they get knocked off.
Others work on too much light is barely enough. Wanting to see 3klm down the road, or at last to the next hump or bend anyway.
Both burn the retinas out of the car in front, or behind. Usless in a convoy, dust, fog, and rain. And it seems to be largely trend, market, or magazine driven.
First the spotties on the bbar up front for ages, then lay back banks of soptties on roofs, then spotties on top of the bbar up front, then fixed spottie banks on roofs, now it's light bars.
Just get yourself some spotties, price, numbers, size, bulb structure is mostly irrelevant. But no matter how much you pay, the % of time they are actually used doesn't make sense for most of us. Just when you finally do use them they work a treat.
