GREAT VALUE + SUPER PERFORMANCE: High power 7W LED light bulb designed specifically for tight spaces of many powersports applications. Works just as well in automotive applications. Brighter than 21W standard bulbs. Omnidirectional design fills in the reflector housings well.
POWERSPORTS: Standard fitting for almost all automotive and motorcycle applications. Works really well for Harley taillight bulb replacement. Choose white color LED if bulb is illuminating license plate. Not DOT approved. Pricing is for a pair of bulbs.
LOAD EQUALIZER: When converting turn signals from stock halogen bulbs to LEDs in some applications load equalizers must be added to avoid hyper flash. This is due to LEDs drawing so much less power that the flashers do not register any load, therefore showing a fast flash warning the driver that a bulb is out. Run/brake lights do not require load equalizers (LE for short). CyronMotor offers electronic type LE products for several models of motorcycles. We do not suggest the resistor type LE because it will generate excessive heat. It will be unsafe and waste electrical power. Brake/run lights normally do not need LE.
HYPER FLASH: Is hyper flash safe for my ride? American regulations (DOT) require turn signal flash rates between 1 to 2 flashed per second. Anything faster than that is technically not legal for public roads. Many studies have shown that faster flashes get more noticed on the roads. One of the reasons flash rates were set to no more than 2 times per second (2Hz) is that incandescent bulbs could not cycle on-off any faster, needing time to heat up and glow bright. Nonetheless, electrical relays in vehicles can flash at faster rates without issues. Our suggestion is that if you decide to stay with hyper flash, do not mix and match turn signal LEDs with stock bulbs, otherwise stock lights will not flash too well.
More vehicle makers are changing their ECM to be compatible with LED lights. Below is a partial list of Harleys that do not require LE when converting to LEDs.
