LED and HID vehicle lights
Work lights / driving lights / LED spot lights / flood lights / HID headlights / LED light bars and interior LED lights
MASAI LIGHTS stocks a wide selection of LED and HID vehicle lights / work lights / driving lights / LED spot lights / flood lights / HID Headlights / LED Light Bars and interior LED Lights. We have high-luminosity LED lights and ultra bright Xenon HID lights, IP65 and IP67 compliant. Some have housings made of die-cast aluminium and others are ABS plastic. Most have wide voltage ranges.
18 to 300 watts and up to 24,000 lumens LEDs. High intensity Epistar LEDs are energy-efficient compared to filament or halogen lights and CREE LEDs are even more powerful and energy-efficient than Epistar LEDs. If you're running additional lights off a switched off engine, then high-efficiency HID and LED lights will drain the battery slower than traditional filament or halogen lights.
About Masai
Automotive Engineering since 1953
Masai is a retail brand name of our design and manufacturing company Omega Automotive Ltd, owned and managed by the Kuman family based in England and Turkey. Since 1953, a passion for automotive engineering has flowed through 3 generations of the Kuman family.
We are specialists in Windows, Metal Fabrication, Lighting, Vehicle Instrumentation, Suspension, Rubber and Cooling. We also manufacture and supply to many automotive companies around the world. See all our products on our other website at Masai.co. Or stay on this website and see them here.
We have facilities in two of Europe’s long established centres of automotive engineering - Istanbul, Turkey - manufacturing, and The Midlands UK (Lichfield) - our Northern European distribution centre.
There's been a growing demand over recent years for vehicle lighting which consumes less power and is far longer lasting than conventional filament bulbs.
LED lights very much meet that need, and for the same power consumption will produce greater luminosity and a whiter light. Recognising that, we have sourced high-quality LED and HID vehicle lights from around the world and will be bringing further ranges over the coming years.
High intensity Epistar LEDs are energy-efficient compared to filament or halogen lights and CREE LEDs are even more powerful and energy-efficient than Epistar LEDs.
If you’re running additional lights off a switched off engine, then high-efficiency HID and LED lights will drain the battery slower than traditional filament or halogen lights.
The circular light you see below is a 4-inch LED work light producing 2,150 lumens at 27 watts with 9 Epistar LEDs. It can be fitted to a wide range of commercial and domestic vehicles.
