NORTHERNLIGHT 42.5 Inch LED Lightbar

This 42.5 inch Northernlight LED light bar delivers 16,353 real measured lumens from 80 x 3W Osram LED chips, run through a shaped lens rather than reflectors for tighter beam control and less light loss. The straight cast aluminium housing includes a stainless steel breather valve that lets the unit vent without letting moisture in, and a sturdy aluminium mounting bracket is included.

Running on a wide 10-30V input, this 240W light bar suits tractors, harvesters, trucks, 4x4s and boats alike. The combo beam pattern (15-30° spot plus 60-90° flood) gives both distance and spread from a single unit, useful for headland turns, yard work or towing at night.

Compatibility

This light bar is based on a standard bolt-on aluminium bracket and a 10-30V electrical system, rather than a brand-specific fitting.

Because of this, it suits a wide range of machines and vehicles where the mounting bracket and voltage range match, including tractors, harvesters, trucks, trailers, 4x4s and boats.

Also suitable for other machines?

Yes. As this light bar is universal rather than model-specific, it can be fitted to any machine or vehicle where the bracket and 10-30V supply match your setup.

If in doubt, contact us for advice before ordering.

Why IP67 and CISPR Class 4 matter

IP67 rating:
An IP67-rated housing is sealed against dust and can handle temporary submersion, which matters on a light bar mounted low on a tractor, ute or trailer where it’s regularly exposed to mud, rain and pressure washing. Without this rating, moisture ingress is one of the most common causes of LED failure in agricultural use.

CISPR Class 4 (EMC):
This light bar is suppressed to CISPR Class 4, the automotive standard for radio frequency interference. Without proper suppression, LED drivers can cause static or interference with the cab radio, GPS receiver or two-way radio — CISPR Class 4 suppression avoids this.
