Here at Project LM, you’ll find a great lineup of light bars, including these 42” combo beam light bars that emit 19, 200 lumens. They offer the best of both the flood and spot beam worlds. The flood beam gives you a much wider lighted area, while the spot beam offers a more concentrated and longer path of projection.

These combo lights are ideal for use by those who drive a larger vehicle that needs more lighting. Here at Project LM, we only offer the highest quality light bars, and do so at an affordable price. Here’s why you can count on Project LM for all of your light bar needs.

s line LED light bars


  • Top quality Cree LED bulbs
  • Heavy duty polycarbonate lens
  • Military quality die-cast aluminum housing
  • Limited lifetime warranty
  • P68 rated as they are waterproof, shockproof, and anti-corrosive
  • Military grade breather



Where you’re really going to see the difference in performance and quality when it comes to LED lighting is the type of LED bulbs used. In all of our products, including the LED combo beam bars, we only use Cree LED bulbs. As our customer, you’ll only get the best and won’t ever have to settle for low-end, generic bulbs in your LED light bars.


aircraft grade aluminum housing

Each one of our combo light bars are housed in a high end, aircraft quality aluminum heat sink housing. This extremely durable housing offers protection in the most trying conditions. These housings have been facility and real life tested to ensure performance. In addition, included with the light bars are stainless steel hardware and mounting brackets.


The international protection standard denotes a level of rating for light bars (and other products). Our light bars are all IP68 rated — which is the highest level rating for light bars. This means that all of our light bars are dust-tight (6) and waterproof (8) when immersed in up to 1 meter of water. Many other brands are only rated at IP67 (cannot be fully immersed in water at any level) or the even lower IP57 (they’re only dust protected, not dust proof).


Because we're so confident in our materials and manufacturing process, Project LM offers a limited lifetime warranty against manufacturer defect on all our products. For more information, visit our warranty page here.


military standard breather

The military grade breathers used on all of our light bars will prevent moisture build up — moisture build-up can and will ruin a light bar. As you travel and the light bar experiences atmospheric changes, this breather will keep the pressure the same from the inside to the outside at any condition. This innovative feature is not seen on many light bars around.
