The brightness of a light bar is measured in the unit of illumination, i.e., lumens. A higher lumen rating will result in a brighter light.

The trend is that the brighter the bulb, the higher the price. The first thing to consider is how much brightness your vehicle actually needs.

Standard headlamps that come with the car provide approximately 700 lumens for the low beam and around 1200 lumens for the high beam. There are some light bars that produce several times this illuminating capacity. You probably will not use such a powerful light, but this could be helpful while driving through total darkness, for example on a mountain road with many turns. The bright LED light bar will warn other drivers of your presence while the driver can clearly see the road ahead of him.

Light bars also have different colours of light which tend to be white most commonly but can also have an amber or blueish tinge. A lumen rating of around 2000 should be sufficient for any vehicle and will provide adequate illumination.

A set of adjustable mounting brackets will ensure that the light bar can be installed on any part of the car, just by drilling holes to fix the bracket.

Sometimes the position of aftermarket lights can be restricted by state laws, with authorities outlawing light bars that interfere with safe driving. Ensure that the placement of your light bar is legal and will not obscure your vision or the sight of other motorists.

Beam Focus

Light bars have a wide variety of beams that can be used in different application. For regular road use a driver beam is useful because it mimics the OEM headlights and is focusses low on the ground.

An off-road focussed beam has a wider angle and focused straight ahead to give the driver a longer range of visibility.

Flood beams have the widest angle of illumination and can be used in search and rescue operations, camping and when there is an absence of street lights.

Some riding conditions require near visibility while other situations require far visibility. Choose the beam focus that best suits your driving style and situation.
