As good as HID, but instant lighting.
I have to say I’m amazed also. I have bought other LED bulbs in the past and was never pleased with the overall results. I watched an hour long video on YouTube from a guy who explained exactly what you need to look for in a LED bulb - a narrow set of chips and minimal thickness between each side, so that the LEDs accurately replicate the original filament of the build you’re replacing. These bulbs do just that. I’ve fitted them to a 2014 Insignia, and had to make one small adjustment ( I had to file about 5mm off one corner of the heatsink) to allow the cap to close on the back of the headlamp. Other than that, I installed the chips facing sideways. The driver unit fits neatly inside the headlamp unit too. The beam pattern is absolutely excellent. Nice crisp white colour that totally matches the stock DRL LED. I’ll never buy another LED that doesn’t match this style. A friend with the same car had to remove aftermarket HIDs at MOT, and I’m hoping these will be a different story, but won’t know for another few months.
