Review on 🔦 HIKARI 2022 HyperStar H4/9003: High-Performance Wireless LED Bulbs with 20000LM, Dual Beam, and Wide Driving Vision by Devin Girard

I just installed 2021 Acme X HIKARI LED bulbs in my 1962 Austin Healey Sprite. I replaced an old set of 2018 HIKARI light bulbs that were starting to flicker as I had been using them for too long with the voltage regulator for the car's alternator set too low. The new bulbs seem like a nice upgrade, they're a little whiter. Color compared to the bluish cast of older lamps. Nice that the drivers are now integrated into the lamps and not in separate blocks, unfortunately the lamps have become much longer as a result. They fit exactly into the headlight shells. For future product improvements, I suggest reducing the length, perhaps by increasing the diameter. See attached images for lamp geometry comparison. Another nice improvement over the old bulbs are the quieter fans, when the new 2021 bulbs are on I can barely hear them. The old fans with 2018 bulbs were loud enough to hear the roaring idle of a 59 year old engine. The light pattern is much more even than with older lamps. I installed them in Cibe H4 style 7 inch round cases. I chose HIKARI lamps twice because of their energy efficiency. Austin Healey Sprite's electrical system doesn't have much power available, they are more efficient. than factory potted incandescent bulbs and produce significantly more light. The electrical system in my car is positive ground, I switched on a relay to switch the ground to negative and the signal to positive.
