FAQs
Does the light come with batteries?
Yes, the Topeak Redlite Race comes with two CR2032 coin-type lithium batteries included.
Can I mount this on my helmet?
The provided straps are specifically designed for seat posts and seat stays and may not provide a secure fit on a helmet.
Is the light waterproof?
The light is designed to be weather-resistant, meaning it can handle rain, but it should not be submerged in water.
How long do the batteries last?
You can expect 60-70 hours in constant mode and 100-140 hours in blinking mode.
What is the weight of the unit?
The unit weighs approximately 37 grams.
Will this fit an aero seat post?
The straps are designed for standard circular tubes between 25.4mm and 34.9mm. It may not fit non-circular aero seat posts securely.
Troubleshooting
Light fails to turn on
Check that the CR2032 batteries are seated correctly and that the protective battery tab (if new) has been removed.
Dim light output
The battery voltage is likely low; replace both CR2032 batteries with fresh ones.
Light slips on the seat post
Ensure the rubber strap is clean and dry. If the post is particularly slippery, a small wrap of electrical tape underneath the strap can provide extra grip.

Setup, Compatibility & Care
Installation of the Redlite Race is straightforward. Choose one of the two provided rubber straps based on the diameter of your seat post or seat stay. Hook one end of the strap to the light body, wrap it around the frame tube, and hook the other side securely.
- Compatibility: Supports tubes between 25.4mm and 34.9mm.
- Battery Maintenance: The light operates on two CR2032 coin batteries. To replace them, open the light housing carefully using a coin or small screwdriver. Ensure the new batteries are seated correctly with the positive (+) side facing up according to the interior markings.
- Care: Wipe the lens periodically with a damp cloth to remove road grit. Although the unit is weather-resistant, avoid submerging the light in water.
