Someone mentioned earlier about adding metal to your factory glare cap to reduce glare. But I thought the bottom part of the reflector produced the most glare.

What parts of the relector would produce glare? Are there any diagrams out there that show this?

I'm thinking about adding to the glare cap but I don't want to cover too much of the bulb. Where should I place the metal to get a halfway decent cutoff?

The bottom part of the reflector does produce the most upward glare, which not only bothers oncoming drivers, but also produces veiling glare for you, in all but the most perfect atmospheric conditions. The other glare is to the left side that affects oncoming traffic. Excess light reflected from the right side of the bulb will affect oncoming drivers.

Thanks,

Now does this apply when you are using D2R bulbs? Or do you still need to add extra sheilding?

It varies with the headlamp reflector design, but every factory D2R application I've seen has at least a frontal glare shield, with some wraparound on the sides, top & bottom. If you look at a D2R capsule and its masking, you'll see that the arc portion is still pretty much exposed.

Yeah I have a front glare cap...but I'm thinking I may need a small wrap-around shield in the back...kinda like the casper shield does:



By the way, I have D2R and I have an 01 Toyota Camry w/9006.

if you have built-in shields, just try your HID lights that way. You may be lucky. If not, put the halogens back in until you figure out the proper shielding.
