LED Lights for Harley-Davidson Road King — Complete Upgrade Guide
The Harley-Davidson Road King is the classic American Touring motorcycle — a naked, chrome-laden bagger with the 7-inch headlight mounted proudly in an exposed nacelle up front. Unlike the Street Glide's fairing-mounted setup, the Road King's open headlight position means every upgrade is immediately visible, making the LED conversion one of the most satisfying mods you can do to the bike.
LOYO offers a full Road King LED lighting kit covering all three primary positions: the 7-inch headlight, the 4.5-inch passing lamps on the lower fork legs, and the front and rear turn signals.

Headlight Upgrade — 7-Inch Round LED
The Road King's exposed nacelle is designed for a standard 7-inch round headlight — the same size used across most Harley Touring and Softail models. LOYO's 7-inch LED headlights deliver 6,000–8,000 lumens of output, replacing the stock halogen's ~700-lumen performance with a focused, DOT-compliant beam that lights up the road without blinding oncoming traffic.
Available in honeycomb, Dragon Eye halo, and standard projector styles, in black or chrome housing. All include built-in CANBUS/EMC modules to prevent flickering on Harley's CAN bus electrical system.
Passing Light Upgrade — 4.5-Inch LED
The Road King's fork-mounted 4.5-inch passing lamps are a direct bolt-on replacement with LOYO's 30W Osram LED passing lights — no drilling, no rewiring. With 2,880 lumens of output, dual DRL and full-bright modes, and a choice of black or chrome bezel, these are the natural complement to a 7-inch headlight upgrade on any Road King.
The chrome bezel finish is particularly popular on Road King Classic and Road King Special owners looking to maintain the bike's traditional touring aesthetic.
Turn Signal Upgrade
LOYO offers 2-inch and 3.25-inch LED turn signal kits compatible with the Road King's standard bullet-style mounts. Available in 1157 (front, double-contact) and 1156 (rear, single-contact) configurations — both are direct plug-and-play replacements with 10x the brightness of OEM halogen bulbs and no load resistor required on most Road King models.
Installation Notes
All LOYO Road King headlights include a built-in CANBUS/EMC module — critical for Harley's CAN bus electrical system to prevent dashboard warning lights and bulb-out errors after installation. The headlight swap takes 20–30 minutes; passing lights take under 15 minutes. No cutting, no splicing, no extra decoders needed.
For Road King Classic models with a chrome nacelle trim ring: an adapter ring is included in the LOYO headlight package to ensure a secure, rattle-free fit.
