If you’ve just found out your car failed its WOF because of dodgy headlights, don’t stress. Happens all the time, especially with Hamilton’s wild mix of foggy Te Kowhai mornings and those blindingly bright summer arvos out on River Rd. Headlights aren’t just there to make your car look good — you need them to see properly when the sun’s gone down or you’re crawling along Wairere Drive in winter drizzle. Plus, they’re a common WOF snag. At Grimmer Motors, we see all sorts of headlight dramas every week, from Riverview to Cambridge and out to Morrinsville. Here’s what we do to get your headlights sorted and keep you safe (and legal) on the road.

Headlight Restoration Service

Cloudy Lenses? We Can Clear Them Up

One of the big reasons cars — Nissan X-Trails, Hyundai Tucsons, even the odd old Lexus RX300 — fail their WOF in Hamilton is because the headlight lenses have gone cloudy or yellowed. Between all the dust on Lorne Street, rough potholes in Glenview, and brutal UV from our summer sun, it’s a wonder any of them stay clear.

If you’re finding it hard to see at night or your lights just look dull, it’s probably the lenses, not the bulbs. Our techs do a full headlight restoration — sanding, polish, and a tough new protective layer. Most people reckon their lights look close to new after. Visibility’s heaps better, and WOF inspectors are much happier too. Learn more about headlight restoration.

Headlight Bulb Replacement

Blown Bulbs? Swap to Something Brighter

Dead or fading bulbs are classic WOF fails. Plenty of Toyota Corollas, Mazda Demios, European stuff like old Renault Scenics and even a few SsangYongs from Tamahere and Rototuna pop in with this one. If you notice one looking dimmer than the other (or out completely), don’t wait — it can make night driving downright sketchy.

We keep a range of bulbs in stock — halogen, LED, and HID — to suit your ride. The upgrade can make a big difference. You’ll see more and get spotted by other drivers quicker, too. That means safer driving, heaps better for the morning commute along Ulster St or foggy runs through Horsham Downs. Know your basics? Here’s a quick headlight maintenance rundown. And for bulb options: check out what we offer.

Electrical Faults Diagnosis & Repair

Headlights Not Working? Might Be Wiring or Fuses

Sometimes you swap the bulb and…nothing. That’s when it’s likely electrical. We see this mostly in older Hondas or the odd Euro import from Huntly, but honestly, it can hit anything on a rough patch over the speed bumps on Thomas Rd. Fuses blow, relays fail, sometimes there’s corrosion in the wires. If you’re having random headlight flickers or nothing at all, our technicians have the gear to track it down fast and fix it.

Headlight Alignment Adjustment

Lights Pointing the Wrong Way? Let’s Adjust Them

Misaligned headlights are another classic WOF trip-up. You’ll notice your beams shining too high (annoying everyone driving towards you on State Highway 3) or lighting up the gutter instead of the road. This happens heaps after a minor bump or just bouncing over those massive speed ramps in Dinsdale, especially in heavier wagons like Subarus or Isuzu Mu-Xs.

Don’t try eyeballing it. We’ve got proper tools to get your lights aimed bang on to the manufacturer’s specs. Much safer for you and everyone else. Find out more on headlight alignment here.
