  • Product Details

The MIDCARS G18-20L is an industrial-grade miniature globe LED replacement engineered for commercial vehicles, passenger cars, motorcycles, forklifts, and marine vessels. Featuring 20 perimeter-mounted SMD 3014 LEDs encapsulated within a rugged, optical-grade polycarbonate globe lens, it produces 160 lumens of clean, full-coverage 360° radial light while drawing merely 2.0W of power. Built with a nickel-plated brass BA15s base (and fully available in BA15d dual-contact or BAU15s 150° pin configurations), the G18-20L is the ultimate solid-state upgrade for aging tungsten R5W, R10W, 67, and 89 incandescent bulbs.

Key Engineering Advantages

1. Protective Polycarbonate Globe Enclosure

Unlike fragile glass bulbs that shatter during heavy chassis vibration or installation handling, the G18-20L incorporates a high-impact polycarbonate shield over the entire emitter array. The clear lens preserves maximum optical transmission while isolating internal surface-mount circuitry from airborne moisture, dust intrusion, and mechanical contact.

2. 360° Cylindrical Optical Dispersion

Configured with 20 high-efficiency SMD 3014 LEDs arranged in a radial perimeter and forward cap, the bulb projects an omnidirectional light pattern that fully illuminates shallow interior dome diffusers, license plate light housings, and side marker lens optics without dark spots or directional shadowing.

3. Discrete Voltage Architecture for Broad Compatibility

Engineered with dedicated voltage regulators tailored to specific vehicle electrical platforms:

  • 6-15V DC Version: Calibrated for 6V vintage motorcycles and classic cars, plus standard 12V automotive electrical systems.
  • 10-36V DC Heavy-Duty Version: Engineered with transient voltage protection for 24V commercial trucks, buses, trailers, and earthmoving machinery.
  • High-Voltage Custom Builds: Tailored voltage architectures available for 48V-85V electric forklifts, automated guided vehicles (AGVs), and golf carts.

Comprehensive Base Options & Series Blueprint

To ensure 100% plug-and-play fitment across diverse vehicle sockets, the G18-20L series offers three interchangeable bayonet base formats alongside standard factory packaging:

Primary Vehicle & Industrial Applications

  • Automotive & Commercial Vehicles: License plate lamps, side marker clearance lights, instrument cluster backlighting, glove box illumination, and front parking lights.
  • Motorcycles & Powersports: Rear tail running lamps, license tag illuminators, and turn signals (RY10W BAU15s amber option).
  • Marine & Recreational Vehicles (RVs): Cabin reading lights, courtesy step lights, and anchor/navigation fixture retrofits (utilizing BA15d dual-contact base).
  • Material Handling Equipment: 24V-80V forklift warning markers, operator cabin dome lights, and warehouse logistics AGV status signals.

Frequently Asked Questions

What is the primary difference between BA15s and BA15d for G18 bulbs?
BA15s features a single center electrical contact at the bottom and uses the metal side casing as the ground return. BA15d features dual center electrical contacts on the bottom with 180-degree parallel side locking pins, commonly utilized in marine, RV, and isolated electrical systems. We manufacture both configurations under the G18-20L platform.
Can the G18-20L directly replace an incandescent R5W or R10W bulb?
Yes. The G18-20L matches the physical 15mm bayonet socket dimensions and miniature globe envelope of traditional R5W and R10W halogen lamps, providing identical optical alignment while reducing power consumption from 5W/10W down to only 2.0W.
Does this bulb require external load resistors to prevent vehicle hyper-flashing?
When installed in auxiliary circuits such as license plate lights, side markers, or interior domes, it is 100% plug-and-play without resistors. When installed as an exterior turn signal on vehicles with thermal flasher relays or sensitive CANBus bulb-out monitoring, an external load resistor or electronic LED flasher relay may be required.
What color temperatures and wavelengths are available for commercial orders?
We offer pure white (6500K), warm white (3000K), brilliant red (620-630nm for rear marker/tail applications), and amber yellow (595-600nm for turn signals and clearance indicators).
