Just installed a set of Narva LEDs - impressed so far. Need to go to Holden to get the headlight error code cleared.
Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.

The ADR/EU headlamp standards define how and when error codes should be raised for differing lighting types and their fault conditions.Just installed a set of Narva LEDs - impressed so far. Need to go to Holden to get the headlight error code cleared.I understand they could do this, but would be very surprised if they would. Let us know what they say.

Why Most LED Headlight Upgrades Don't Really Work: An Expert Explains
I got a stern talking-to from an actual lighting expert about LED retrofits.jalopnik.com

Other than quality halogen globes and correctly aimed beam Or much more complex and expensive OEM LED retrofitOEM HID should be the only thing you consider.

Problem is that some simply want something different and modded within their car, at an affordable price, regardless of whether it’s actually better and safer than OEM or even appropriate for road use
The problem for many consumers is that they’re paying more for the LEDs but not getting much bang—if any—for that extra buck, says Jennifer Stockburger, director of operations at the Consumer Reports Auto Test Center.
“Yes, they’re stylish, but drivers need lights that will make them safer, and not just make a fashion statement,” Stockburger says. “Car shoppers need to think about headlights as a safety feature in the same way they think about brakes or even seatbelts.”
Both LED and HID headlights can produce a brighter, whiter light than halogens, and they illuminate the sides of the road well. But how far a headlight illuminates straight ahead, in the direction a car is traveling, is what’s most important, Stockburger says. In that respect neither HIDs nor LEDs have proved to be superior over halogens in CR’s testing.
“Even with the new technology, low-beam headlights don't always provide enough forward seeing distance for the driver to react to an object in the road and stop in time,” Stockburger says.
For example, CR’s brake testing shows that, on average, a vehicle traveling at 60 mph (or 88 feet per second) on dry asphalt in ideal conditions needs about 130 feet to come to a complete stop. Estimates for a driver’s reaction time between seeing something ahead in the road and hitting the brake pedal is 2.0 seconds—at roughly 88 feet per second, the vehicle has traveled 176 feet before the driver has hit the brakes. That means the total distance needed from recognizing an object to coming to a full stop is about 300 feet.
But in our headlight tests, we’ve seen that neither LED nor HID low-beam headlights consistently illuminate more of the road ahead than halogens do. The poorer performers among all headlight types don’t reach the 300-foot mark. The result is that drivers traveling at 60 mph or faster will “overdrive” their headlights, meaning they're going faster than the lights can illuminate the road ahead, giving the driver little time to stop. The Escalade we tested in 2015 was able to illuminate signs on our headlight test course as far as 400 feet ahead.
