they are pretty good, and please follow the recommended procedure for handling any halogen lamp bulb, If you suspect that the bulbs glass is contaminated by skin oils then wipe off with alcohol wipes, Ive used this practice since I was introduced to cars. I just use them regardless, wipe them clean and lock into place.
The best quality bulbs I bought in Pakistan were Koito of Japan, very hard to find now, and then later Osram, do not buy chinese garbage bulbs - as they can fail when you need them the most - imagine them failing right on GT road at 10PM.
