Let's Face it: So many modern vehicles are still using incandescent bulbs in their turn signals, parking lights and brake lights that the world just isn't quite ready to move on from plug n play LED Bulbs. Despite that, the category has been stagnant for years with little to no real innovation or upgrades... until now. The new XB LED Bulbs are a much-needed refresh in this category and are all new for 2023!

Unbeatably Bright: The 3156/3157 XB LED bulbs are great for turn signals, parking lights, brake lights, and tail lights, brake, and tail lights. With 30w of power, they are incredibly bright too, making for an instant upgrade in performance, style, and safety no matter where you put them to use.

Resistor-Free: The XB LED bulbs do not need any extra resistors and they won't cause any hyper-flashing on your turn signals either! Unlike other "resistor-free" LED bulbs that have been on the market for a while now that dim down and start hyper-flashing within a minute or two, these will maintain their resistor-free nature AND their intensity for well over 30 minutes, all without any overheating or reliability issues.

CK or Non-CK: These bulbs are conveniently compatible with both CK and non-CK Circuits, so there's no need to take a multi-meter and a friend out to your truck just to ensure you're buying the right version. The electronic system is universal for both.

Heat Management: is crucial for reliability when it comes to anything LED. High wattage means high surface temperatures, but the integrated fan works well to keep hot air away from the internal cavity of the bulb. The XB LED Bulbs do a great job at keeping the critical components such as the circuit board and LED chips cool, and therefore reliable.
