Why Every Towbar Bike Rack Needs a Light Board (And It's the Law)
Driving with a loaded bike rack can block your vehicle's number plate and tail lights, putting you at risk of fines and reduced visibility. A quality light board with supplementary lights and a clear plate panel keeps you compliant and safe on the road. Discover the best options at the right price.
If you've ever strapped a couple of mountain bikes onto your towbar rack and driven off without a second thought, you're not alone. Most Kiwi drivers don't realise that a loaded bike rack can hide their number plate and lights, and that this is actually against the law. Let's break down why a bike rack light board isn't just a nice-to-have, it's essential.
The Problem With Standard Bike Racks
Towbar mounted bike racks are brilliant for getting your bikes to the trailhead, but they almost always sit directly in front of your number plate and tail lights. Add a couple of bikes into the mix, and your brake lights, indicators and plate can be completely obscured from the driver behind you.
That's a serious safety issue. If the car behind can't see your brake lights, they have far less warning when you slow down or stop suddenly.
What New Zealand Law Actually Says
According to NZTA rules, it's illegal to obscure your vehicle's lights or number plate while carrying bikes. Here's what you need to know:
- Your lights must be visible from at least 200 metres in clear weather.
- A supplementary number plate is required if your rack blocks your original plate.
- Supplementary plates must be official NZTA plates, fixed to a hard, flat surface, and illuminated at night. No cardboard, no loose hanging plates.
- Breaking these rules can cost you 20 to 25 demerit points per offence, plus fines.
Beyond the legal risk, think about what's actually at stake: your safety, your family's safety, and the safety of everyone driving behind you.
The Simple Fix: A Quality Light Board
This is exactly where a bike rack light board, like the Safelite Panel, earns its keep. Designed and built in New Zealand, it's made specifically to solve this problem for Kiwi drivers carrying bikes.
What Makes a Good Light Board
- Universal fit: Suits virtually every bike rack sold in NZ, with mounting holes from 31 cm to 52 cm.
- Fast fitting: Heavy-duty bungee cords with easy-lock toggles mean it's on and off in seconds, no tools required.
- Built tough: UV-stable, waterproof aluminium composite that handles rain, dust, salt spray and NZ roads.
- Plug-and-play wiring: A 1.4 m cable with a standard 7-pin trailer plug connects straight into any standard NZ towbar socket.
- Number plate ready: Pre-drilled holes and bolts supplied so you can fit your NZTA supplementary plate properly and stay road legal.
- Backed by a two-year warranty, so you can buy once and buy right.
Protecting More Than Just Your Bikes
Modern bikes aren't cheap, and neither is a rear-end collision. A light board protects your investment by making sure the driver behind you actually sees your brake lights before it's too late.
Final Thoughts
A bike rack light board is a small addition that makes a big difference, keeping you legal, visible and safe every time you load up the bikes. If you're heading out for a weekend at the trails or a weekday ride after work, it pays to have your lights and plate sorted properly.
