Profile Performance: It's not like LED bulbs in the automotive world are a new thing, but these guys are coming in hot and packing a serious punch with the new Crown series. Lucky for us they're still offering some value-minded options that won't break the bank, but don't mean much compromise in the performance department too. Though they cost a few bucks more than the 1.0 series, the Crown T10 2.0 is a killer choice with their refined optic, Philips Lumiled LED chips, and copper/ceramic housings. Multi-Use: With more intensity than the original halogen bulbs, the Crown T10 2.0 LED bulbs make for an awesome upgrade in performance and style. If you're looking for something brighter and whiter: then you can pick up a set of Crown's that will be perfect in many positions on your car. They are ideal for use in corner and side markers, license plate lights, city lights, and are easily the most popular size for interior lighting too. Diffused: acrylic lenses on the tip of each bulb help distribute light evenly through the face of the bulb. Compared to other options like the Crown T10 1.0's or the side-firing Morimoto's, the Crown T10 2.0 produces a very smooth evenly distributed beam of light. They're most like the Osram LEDriving T10's - which are one of our most popular sellers! Mated: Two-piece construction combines resin and copper to shed heat. Housing an internally regulated circuit (that accepts dimming) will keep the T10 Diffusers running reliably virtually forever! CanBus: The Profile Crown LED bulbs are CanBus friendly and shouldn't cause any dashboard errors in most every application. No need for extra resistors or inline modules to resolve that. Just Plug n Play! By the Numbers: One high powered 6000K Philips Lumiled white LED chip. 120 lumens per bulb. 360 degrees of light through the diffuser optic. 7.5 bucks per bulb. All of that should add up to one happy customer!
