LED Auxiliary Lights for Motorcycles

Why are auxiliary light needed?

Safety: If you are a serious tourer, you will appreciate the fact that brightly illuminated roads are safer. Most stock lights are either weak or do not provide a good spread or throw. The problem multiplies during rains or when the roads are wet and become darker. Aux lights can also act as DRL boosting day time safety.

Confidence: That’s when an auxiliary light pair can do wonders. It can complement the stock illumination to fill the gaps and boost your confidence in riding at night.

Image Triangle

Image triangle: Another benefit is of showing a larger image to oncoming traffic. With one stock light and two auxiliaries, an image triangle is formed and this gives the illusion to oncoming traffic of a larger vehicle, who will then give you more space increasing the safety margin for you.

Technologies: LED vs HID vs Halogen

Stock lamps are halogen bulbs which generate a yellow light of about 2800K to 3000K (K = Kelvin, a measure of light color and not brightness). Generally 50/55W or 55/60W is the stock bulb providing just enough illumination.

Many riders upgrade to HID which are normally available in 6000K white-blue color. White light is no good in fog or rain conditions, as it illuminates and reflects on the water particles. Without a projector setup HID’s create a glare to oncoming traffic and make it unsafe for the rider as oncoming traffic is blinded! Another side effect of HID is strain on stock electricals due to the high startup current. The best option is a 4000K (or even lower K) HID with a good projector lens in a stock housing or an aux housing. Projector lenses are heavy and the risk of cracking of the stock casing are high due to this heavy load. Good setups will be very expensive – Morimotos are a good example. 

So overall HID is not a good idea unless a professional quality (read expensive) setup is done. 

RL+ 10W LED pair
Then come LED’s which provide a huge light output for comparatively less power consumption and smaller packages and weights. This allows less stress on stock electricals. But LED’s are generally in the 6000K white-blue color range (but wait we have a solution in the form of yellow conversion lenses) 


Why LED Auxiliaries?

Our philosophy is to never disturb stock electricals and even stock lights – i.e. stock lights should run no matter what. 

RL+ Amber lenses for 35W or 15W LED
Therefore we suggest to add LED lights as true auxiliaries. Using an independent relay harness, power can be drawn directly from the battery and lights can be switched on/off only after the bike engine is running or pilot lamps are on.

The 35W and 15W LED Aux lights by RedLinePlus also have Yellow/Amber lenses available as extra accessories useful during rain, fog or group rides (reduces glare in RVM of your buddies ahead). These lenses can be quickly removed if not needed.


LED options which we provide:

RL+ 35W LED Pair
35W LED – this is spot & wide pattern beam with 4 individual LED’s 
15W LED this is a spot pattern beam with 4 individual LED’s 
10W LED  this is a spot pattern beam with 1 single LED 
5W LED Pilot –  a bright pilot lamp with 5 COB LED’s 


Suggested combinations:



  1. 35W + 35W + 10W + 10WThe works! This combo is suitable for bikes with large alternators like the Kawasaki 650 cc and above or big adventure bikes 800cc and above. Great for the night racers, we call this as your private sun. The 10W are spot pattern and with our digital switch/controller can do strobe and other functions. 
    1. 35W + 35W – Again a high power combo suitable for bigger bikes only 

    2. 35W + 15W – Great power to illumination combo for bikes more than 200cc like Pulsar 200, Duke 200/390, RE 350 and above. 
    3. 35W only – A single combo LED suitable for smaller bikes with a power budget. A single 35W LED is much better than 3 or even 4 10W LED due to electronic devices efficiency and loses 
    4. 10W + 10W – A VFM combo for smaller bikes or for commuters and weekend riders.
