With its compact size, optically correct output, thermally-modeled cooling, and boost-mode electrical circuit, the SL1 LED finally provides a true upgrade in performance.
Street Legal Output. Don't be fooled by high lumen numbers or "projector specific" bulbs. Your car's headlights are designed to focus light. If the light source is out of focus, it doesn't matter how bright it is - you won't have a focused hotspot of light to shine down the road - just more glare. To correct this, the SL1 LED headlight bulb was engineered with advanced optical design software, to perfectly match filament location. This allows the SL1 LED to focus light just like an original bulb, preserving the focus and hotspot, with no added glare. It produces a functional beam pattern on the road, in compliance with photometric standards, for a safe, functional output, which we call Street Legal.

Diode Dynamics has never disappointed me before. I got these for my wife’s Impreza and she loves them. These LED bulbs are excellent for backroad driving. Do yourself a favor and say no to the Ebay no names LEDs. Spend the money once and you’ll see the DD difference.
I have been on the fence about going LED, but finally pulled the trigger. I had no idea how drastic the difference was going to be or I would have done it a while ago. These SL1's are awesome. It's impossible to tell you how good they really are, but if you are looking at them and are on the fence like I was, get them, you will be impressed also. Shout out to Nick also, these got here fast and he always has the best prices.
Super bright and fastest shipping I know
The low beams and the c-lights work beautifully. The added plug and play harness made everything a breeze.
Replaced my 3yr old LEDs with S1 bulbs and all I can say is WOW. Just the right brightness, perfect cutoff. 10/10,would buy again.
