Review on 2PCS GOOACC D1S HID Bulbs With 6000K Cool White, 35W High/Low Beam For Xenon Headlights - Upgrade Your Car'S Lighting by Bob Boan

Pros: Great price; huge improvement over my OEM bulbs that were going on eleven years old (see pic showing new bulb on driver side, old bulb on passenger side); love the 6000K color temp, the bluer light does a much better job of illuminating the darkness, imo.Cons: Aside from the frustration I experienced in changing the bulbs myself (Infiniti does not make this job easy - they'd rather you take it to them so they can charge you $500 for the job), the only con here is the lack of response from customer service. I emailed a question about whether or not these were high & low beam bulbs (this info is hard to ascertain & I didn't want to have to do the job twice if these didn't work for both functions), and never got a response. If you're using these on an Infiniti, they do indeed work for both high & low beams.Conclusion: Happy with the price, happy with the functionality. Just changed these out a week ago, so if they disappoint in any way in the future, I'll be sure to update this review!
