D03 vs D09 Pro: Which Colight Motorcycle Auxiliary Light Is Best for ADV Riders in 2025?

Best Motorcycle Auxiliary Lights for ADV and Dual-Sport Riders

 

Over the past year, two Colight motorcycle lights have stood out among ADV and dual-sport riders: the compact 3.5-inch D03 and the feature-packed 4.5-inch D09 Pro.

Both lights quickly became favorites across the ADV community, supported by reviews and real-world testing from creators such as RiderCam TV, Bavarian Bloodhound, The Stammering Biker, KAMAIL WORKSHOP, and Loraand.

But which one truly deserves the title of Colight’s Best Motorcycle Auxiliary Light of 2025?

To find out, we compared the two lights across five key categories:

  • Sales performance

  • Real-world road illumination

  • Beam pattern design

  • Price value

  • Expansion and compatibility

Each category is scored out of 20 points, for a total of 100 points.

Let’s break down the numbers and see which light comes out on top.

Sales Performance

  • D09 Pro: 14.2% of total motorcycle light sales

Both lights rank #1 and #2 overall in unit sales.

Revenue Contribution

Expansion & Compatibility

Many ADV riders integrate their lighting with Hex ezCAN, one of the most popular motorcycle electronic controllers.
Brands like Lone Rider and Denali also offer CAN-based accessories.

Using Hex ezCAN as a reference, here’s how the two lights compare.

D09 Pro

The single-DRL version can connect to Hex ezCAN.

However, because ezCAN uses a dual-channel system, only two of the following can operate independently:

  • High beam

  • Low beam

  • DRL

The dual-DRL version is not recommended for ezCAN integration.

Due to its higher output, it works best when paired with smaller auxiliary lights for layered lighting setups.

Score: 18 / 20

D03

The single-light design connects easily with Hex ezCAN.

It also allows the amber backlight to be configured as a turn signal.

Because of its compact size, riders have more flexibility when building multi-light setups.

Score: 19 / 20

Final Score

MODEL TOTAL SCORE
D09 Pro 94.5/100
D03 94.5 / 100

 

The D09 Pro wins by just one point, earning the title of Colight’s Best Motorcycle Auxiliary Light of 2025.

With multiple versions, the highest revenue contribution, and its high/low beam hybrid design, the D09 Pro clearly reflects its mid-to-high-end positioning and strong performance capability.

That said, the D03 remains a fan favorite.

With the highest unit sales, it proves itself as a reliable, high-value option that resonates with a wide range of riders. Its price-to-performance ratio makes it one of the most accessible upgrades for everyday ADV riders.
