You may recall in my last blog, I recently swapped out the old sealed beam units on my 1966 Gilbern GT for a rather modern set of LED headlights. In theory, the job was fairly simple – same fitment, same connectors, and the physical install was straightforward enough. But in practice, if I wanted to unleash all the cool features these new lights offered – like the crisp daytime running lights and integrated amber indicators – I was going to need a bit of extra help.
That’s where this story picks up.
Getting the LEDs working properly
The headlights were in, but features like the DRLs and indicator function weren’t doing anything. These LEDs are designed so the DRL strip stays white while driving, but switches to amber when you indicate – a nice modern touch that also improves visibility and safety. But wiring that into a 60s car isn’t exactly plug-and-play.
I knew this wasn’t just a job for any regular electrician – I needed an auto electrics specialist. So, I did what anyone would do: hit up Google.
After a bit of digging, I came across Sumners Auto Electrics in Cardiff – a highly rated team who specialise in this kind of work. After exchanging a few emails, I took the Gilbern down to show them what I was working with. They were brilliant – professional, knowledgeable, and clearly excited to see something a bit different in the workshop. They tested the new lights directly on a battery, confirmed everything was working, and got me booked in for a couple of weeks later.
In the meantime, I happened to mention it to one of the other Gilbern owners – and also to Dave and the guys at Rumney Hill Garage. Everyone knew of Sumners and had good things to say. That was reassuring.
The fix
When the day came, Sumners got stuck in right away. One issue cropped up fairly quickly: hyperflashing.
If you’ve ever fitted LED indicators to an older car, you’ve probably seen this. Because LEDs use less power than traditional bulbs, the car thinks a bulb has gone out and starts flashing rapidly to alert you. That’s exactly what happened on the Gilbern.
I remembered the same issue happening years ago on my first Mini Clubman – I’d fitted LED side scuttles and the indicators went haywire until I installed a fix that came in the kit. In this case, Sumners knew exactly what was needed: a suitable LED flasher relay.
They sourced one quickly, installed it, and just like that – job done.
The results
I won’t lie – I was grinning like a kid when I saw them lit up for the first time. The difference is night and day (literally). Bright, crisp, and properly modern, but still in keeping with the Gilbern’s unique look.
The DRLs fire up as soon as the ignition is on, and the indicators now switch over to amber with a sharp, clean transition. It’s not just form – it’s function, too. Visibility is massively improved, which makes a big difference in a car like this.
One thing I hadn’t planned for – with the indicators now integrated into the headlights, the original indicators are technically redundant. I’ve been looking around for some clear covers, maybe off an old Ford or something period-correct, just to keep things clean and tidy. If I can’t find anything suitable, I might have to get creative.
Will everyone approve?
Well, this is where things get interesting. I already know a few Gilbern purists might raise an eyebrow. But honestly, how good do they look? I’m all for keeping the heritage alive – but if you can improve safety and visibility without ruining the character of the car, why wouldn’t you?
What’s next?
With the front end sorted, I’m now eyeing up the rear lights. Do I go full LED back there too? Might be a bit more of a challenge, but you know what – it could be worth it. Stay tuned for Part 3, perhaps…
