I'm here, just been a bit busy lately.
As with all additional lights, you have to decide what your purpose is. If you mostly want other cars to see you, then some smaller, lower wattage lights will work. Or perhaps yellow fog lights for extra visibility (and extra usefulness in dense fog). If you want to see further down the road, then you need more powerful (and thus more expensive) lights.
On my setup, I wanted to see more than be seen. So I went with HID driving lights on a custom bracket.
The bracket is something that Ernie and I came up with in his shop. It uses existing screws near the oil cooler. It bounces a bit more than I'd like, but I have figured out how to make support brackets to minimize that. Just need the time to do it . . .
The lights are PHIDs
, or Phillips HIDs. They have become a staple in the Long Distance community because of their small size and huge output. They're not cheap, but then again, neither is hitting a deer.
I've been happy with the lights overall. I have them aimed so the right one is high and far, giving me a good view of the right shoulder and any critters that may be lurking there. The left is lower and closer so that it still gives a good view, but doesn't annoy most cage drivers. Unless it's a tiny two-lane road with lots of oncoming traffic, I can leave the lights on full time and get great visibility.
The stock high beam actually reaches a little further, but has a weaker, yellowish halogen beam. Converting the high beams to HID also would be a great addition for getting that extra visibility way down the road.
