What to know before buying
Listing details to confirm
Listing details are inconsistent: the title identifies both D1S and D1R, while the model field is D1S, and package quantity is listed as 1 despite the title and item count indicating two bulbs. The listing also describes use with back-up light assemblies while identifying a front position, and its D1S beam-pattern claim does not resolve D1R compatibility. Confirm the socket type and selected pack details before purchase. The 800% brightness and 60,000-hour life are manufacturer claims, not verified performance.
What’s in the box

Customer feedback highlights perceived brightness, quality, value and ease of installation, with some describing a noticeable improvement over their original lights. Fit and longevity are mixed, including reports of incompatible fit and multiple burnouts. For buyers considering the claimed D1S replacement, those reports make vehicle socket confirmation and willingness to accept uncertainty around service life especially relevant. The listing's brightness and lifespan figures remain product claims, not customer-confirmed measurements.
Positive themes
- Customers describe the bulbs as bright and report easy installation.
- Feedback also mentions quality, appearance and value positively.
Mixed feedback
- Customers report mixed fit experiences, with some saying the bulbs fit and others saying they do not.
- Lifespan feedback is mixed, including reports of repeated burnout.
Frequently asked questions
Are these bulbs confirmed to fit both D1S and D1R sockets?
No. The title mentions D1S and D1R, but the listed model is D1S and the supplied details do not confirm D1R fit. Verify the socket required by your vehicle.
How many bulbs are included?
The title and number-of-items field indicate two bulbs, while package quantity says 1. Because those details conflict, confirm the selected listing's pack contents.
What color temperature and brightness are listed?
The details list 6500 Kelvin and 30000 lm. The title and feature text also make an 800% brightness comparison, which is a manufacturer claim rather than a verified measurement.
What do customers report about fit and lifespan?
Feedback is mixed on both. Some customers report good fit and durability, while others describe fit problems or multiple burnouts.
