Frequently Bought Together


LED replacement bulbs can fit vehicle tail lights, brake lights, reverse lights, turn signals or side marker lights. This 7507 (PY21W) single-contact bulb has 18 LEDs (5050 SMD) that create a 360° viewing angle for better, allover light emission with reduced hot spots. Amber lights feature high-intensity LEDs that are ideal for high brightness LED applications. Tower-style design with a 15-mm BAU15S bayonet base and 150° offset locking pins. Easy plug-and-play installation—just twist to lock in place. The energy-efficient bulb operates within a wide 10-30V DC range and is designed to last 30,000 hours on your car, truck, SUV, or van—25 times longer than incandescent bulbs. Available in cool and warm white, amber and red. Includes 1 replacement bulb.

Important Notes - Please read before purchasing:
  1. Your vehicle may require an LED compatible Flasher or Load Resistor. LED brake/tail lamps will not flash with most stock flasher units due to their extremely low current draw. Try our Vehicle LED Bulb Finder to find a compatible flasher for your vehicle. Please See More LED Car Bulb Notes
  2. For best results the LED color should be the same as the lens color. If bulb is behind a clear lens, use the appropriate color for turn and brake light functions. Please See More LED Car Bulb Notes

Diavel Strada rear turn signal replacement

Plug-n-play! Replaces the stock incandescent bulb perfectly and without the need of a load resistor. Throws out lots of light and due to its taller profile it also shines light further above/below/sideways, thus allowing the turn signal to be easily seen from angles more than just from behind.

Does not fit

Order these "plug & play" bulbs for my Triumph Tiger 800 XCX. They plug but won't play as the bulbs are about twice as long as the OEM halogen bulbs.

Everything I Expected

I used these on my VTX 1800 on the rear. I converted the rear (amber bulbs clear lenses) turn signals to function as running lights that flash 4 times when the brake is applied. I also used one in the stock tail/brake housing (red lens). With the brightness of combined with the instant on/off of these LED's, the bike is much more visible from behind! 12k miles and still working flawlessly.

Plug and Play for a Honda Silverwing!

I ride a 2003 Honda Silverwing Scooter everyday. I bought a heated jacket, gloves, and snow shield for my helmet for the winter. I noticed that my headlights were pulsing when I wore my heated gear and my heated gear wasn't at full temp unless the motor was revved up which said to me that it was causing a power drain on my electrical system so I decided to change the OEM bulbs for LED bulbs so that some juice would get freed up. So far, just changing out the turn signal and tail light bulbs has resulted in my heated gear being at full temp from the moment I plug it in and my headlights don't pulse anymore. The turn signal bulbs are indeed brighter and flash a little faster than the OEM bulbs because I didn't buy the resistors which was intentional. I figure that the cagers would notice the faster rate of the brighter lights more than they originally did. The color of the bulbs really pop through my clear lenses too. I'm going to recommend this site to other Silverwing owners.

Love this bulb

I put this bulb my 2018 Honda Accord rear, very bright. Requires the resistor kit to prevent hyperflash.
