Product Overview: G18X-54L14 G18 BA15S / BAU15S Switchback Dual-Color LED Bulb

The MIDCARS&reg; G18X-54L14 is an ultra-compact, high-performance dual-color LED signal bulb specifically engineered for motorcycles and specialty automotive lighting. Built with 54 pieces of high-density SMD 3014 LEDs on an aviation-grade aluminum substrate with molded weatherproof silicone gasket seal to prevent moisture entering the lamp housing, this bulb provides intense 360-degree illumination while drawing ultra-low power.

Designed to directly replace conventional single-contact mini bayonet bulbs (R5W, R10W, RY10W, G18, 5007, 5008), the G18X-54L14 upgrades factory front or rear turn signal housings into a modern synchronized Daytime Running Light (6500K Pure White) and Direction Indicator (595-600nm Signal Amber ) configuration without generating excessive heat.

Smart Dual-Mode Switchback Illumination Logic

  • Daytime Running Mode (DRL): When ignition or parking lights are switched ON, the external power wire energizes the 54-SMD array in 6500K Pure White for clean, continuous daytime visibility.

  • Turn Signal Activated: When the turn indicator or hazard switch is toggled, the internal circuit immediately suppresses the white light and flashes in 595-600nm Signal Amber at the standard vehicle flash rate.

  • Turn Signal Cancelled: Once the turn signal cancels, the bulb seamlessly restores back to 6500K Pure White DRL after an engineered 1.0-second delay, ensuring complete compliance and modern lighting aesthetics.

⚠ Anti-Hyper Flash Recommendation (Load Resistor):
For motorcycles or vehicles equipped with thermal or mechanical flasher relays that experience hyper-flashing due to the low power draw of LED bulbs, adding an external load resistor is recommended to restore factory-standard flash rates:
 &bull; 12V Systems: Add an external 5W 100 Ohm gold aluminum load resistor (or replace with an electronic flasher relay).
 &bull; 24V Systems: Add an external 5W 300 Ohm gold aluminum load resistor.
 Note: The load resistor must be wired exclusively across the Turn Signal circuit and ground. Never connect a load resistor to the continuously-lit DRL circuit!

Target Applications & Vehicle Compatibility

• Motorcycle Upgrades (Primary Focus)

Ideal for adventure bikes, street bikes, cruisers, and maxi-scooters . Fits models such as BMW® Motorrad (F800, R1200, S1000RR), KTM® Duke & Adventure series, Ducati® Monster & Scrambler, Triumph, Honda, Yamaha.

  • Sample Lead Time: Standard stock evaluation samples dispatch within 2&ndash;3 business days; custom prototype batches dispatch within 5&ndash;7 business days.

Compliance Note: CE (EMC) & RoHS certified. Intended for off-road, track, show, or custom retrofit applications. Check your local road regulations regarding dual-color auxiliary lighting before on-road use.

Frequently Asked Questions

What sockets does the G18X-54L14 bulb fit?
It fits BA15S (R5W / R10W, 180° parallel pins) and BAU15S (RY10W, 150° offset pins) mini bayonet sockets, ideal for motorcycle turn signals and car side indicator repeaters.
Does this bulb require external wiring for switchback operation?
It uses a plug-and-play bayonet socket for the turn signal plus a 60cm ACC wire with T1 quick-tap connector that feeds ignition power for the white DRL.
What is the operating voltage range?
DC 12-24V wide voltage, covering both 12V motorcycle / car systems and 24V commercial systems.
What should I do if the turn signal hyper-flashes?
This bulb has no built-in resistor. On thermal / mechanical flasher-relay vehicles, add an external load resistor across the amber turn signal circuit (12V: 5W 100Ω; 24V: 5W 300Ω), or upgrade to an electronic LED flasher relay.
