I drive at night. A lot. I go to work when it’s dark, and then I come home when it’s dark. Aside from being soul-crushingly depressing, it’s also dark. And deer mating season. And ice-on-the-road season. To that end I decided I needed to see a bit better than the $15 sylvania sealed-beams on the Miata would allow. As luck would have it just as the thought popped into my head a clubroadster.com member posted something interesting for sale: A set of Bosch H4 sealed-beam adaptors with a set of Sylvania Silverstar Ultras and, here’s the kicker, some H4 LED bulbs. The owner was upgrading to projectors, which I would do but I didn’t like the non-stock look. Here’s the LED assembly next to a stock sealed beam.
Can’t tell which is which, can you?
Here it is from the back. You can see the small computer fan used to dissipate the heat from the LEDs. These make a very interesting noise that you can hear from outside the car when they’re running.
Let’s have some comparisons...
Sealed beams, then LEDs.
LED and sealed beam. I really like the wider beam. Very good for seeing deer and other stuff off to the side of the road.
Sealed beam and then LED
And a shot from above and below the cutoff to show how little glare there is. I’m very impressed, and flipping the brights on is an instant flash of light which is very noticeable and eye-catching.
And a random shot from behind the wheel just for the hell of it
