This pack includes two LED bulbs compatible with R5W, 1156, 67, 89, 97, 105, 1155, and more. Each bulb features 12 5630 chips that deliver 700 lumens of 6000K white light while consuming only 1.3 watts. Their compact design makes them easy to replace. Suitable for 12V low-voltage vehicles like cars, RVs, and boats, but not for 24V systems. Built-in resistors protect against voltage fluctuations, though a 50W 6 Ohms load resistor or flasher relay may be needed to prevent hyper-flashing. These bulbs are ideal for turn signals, tail lights, license plates, and various RV, marine, and outdoor lighting applications.
