Misplaced your car bulb holder? Whether it's due to a playful pet or an accidental toss, these components can vanish in the blink of an eye. But don't fret, TRS is here to help. Our headlight bulb retainer rings, made of OE quality temperature-resistant ABS, are the ideal replacements for the original units. Designed to secure D1S/D2S bulbs in HID projectors, they're a direct fit. We provide three styles suitable for Bosch/AL and Hella projectors. However, ensure you scrutinize the images for the right fitment, as they can be deceivingly similar. Remember, the price is for one piece, so order two if you need a pair. With TRS, you're not just getting a product; you're investing in quality, trust, and a decade-long legacy in automotive lighting.
