Do You Need a Light Board? A Quick Guide for Bike Rack Owners
Wondering if your bike rack setup requires a supplementary light board? This quick guide breaks down when they're legally required, how they improve visibility, and why investing in one protects both your wallet and your safety while driving with bikes loaded.
Why This Question Actually Matters
If you're loading bikes onto a towbar rack for a weekend at the trails or a family getaway, there's a good chance your rear lights and number plate are being blocked without you even realising it. In New Zealand, that's not just a minor oversight, it's a legal problem with real consequences.
What NZTA Rules Say
According to NZTA requirements, your vehicle's lights must be clearly visible from at least 200 metres away in clear weather. It is also illegal to drive with a number plate that is wholly or partially obscured. When you fit a tow bar mounted bike rack or carrier, it will almost certainly cover your original plate and lights, meaning you'll need:
- An additional light bar or bike rack lights to keep your indicators and brake lights visible
- An official NZTA supplementary number plate, fixed to a hard, flat surface and illuminated at night
Homemade plates or anything scrawled on cardboard simply won't cut it, and loosely hanging a plate at the back of your rack is also against the rules.
The Cost of Getting It Wrong
Driving with obscured lights or plates can land you 20 to 25 demerit points per offence, alongside hefty fines. Beyond the legal risk, you're also putting yourself, your family, and other motorists in real danger. A driver behind you who can't see your brake lights has far less time to react, and that's a risk not worth taking with expensive bikes (or people) on board.
How a Light Board Solves the Problem
This is exactly why products like the Safelite Panel exist. Designed and made right here in New Zealand, it keeps your indicators, brake lights and number plate fully visible the moment your bikes go on the rack.
