Vauxhall/Opel Insignia SRi Headlight Conversion To LED

11/12/2025

Hello Vauxhall/Opel Insignia owners from around the World, I hope you are well.

As the title suggests, in this post, I will be attempting to convert the dipped and main beam halogen bulbs in my headlights with LED replacements.

If you own an Insignia, you might be aware that the headlights are not very good and produce a very dim dipped and main beam headlight. Apparently this is because of a poor headlight design. Although other car headlights produce a decent amount of light with a conventional 50/55 Watt halogen bulb, the (face lift 2013-2017) Insignia produces very little light with these bulbs. Apparently changing the bulbs for a higher power or different type (in this case LED) of bulb does not make any difference to the strength of the light produced. However, I am tired of having such a poor light to help guide me through these dark winter evenings, I am willing to try for any improvement in illumination. 

In my efforts to try and improve my night driving vision, I did extensive research in trying to find a decent replacement LED bulb that would not cause the car to give me error codes. As you can imagine there are literally dozens of types of LED headlight replacement bulbs that advertise that they are error free bulbs, but I have read there are actually only a few that will not produce an error code. After much research, I eventually joined an Insignia owners forum and asked the question to some of the people who might have the answer. The answer I was looking for was a pair of LED headlight replacement bulbs that I could buy from Amazon. The bulbs I needed are D-Lumina HIR2/9012 type that would be a direct replacement for the conventional halogen bulbs.

After receiving the information of the type of bulb and the manufacturer of said LED, I quickly went to Amazon to order the lights. 

When I went onto Amazon I was kind of shocked at the price of the pair of LED replacements. I was expecting to pay maybe £7 to £10 for each LED but they were an eye watering £39.95 for a pair. After further investigation, I found that this was the typical amount for a pair of LED replacement bulbs. The cheapest I could see were on Ebay at a price of £16 each. Again the seller said they would be error free but after checking the whole advert, they could not guarantee this would be the case. After debating with myself for a short while, I decided pull the pin and ordered the D-Lumina bulbs from Amazon, after all I was willing to pay the extra cost for extra illumination for safety reasons and the error free replacements. 

After ordering, I was happy to be informed that the replacement LED bulbs would be with me the next day, which they were and here is what I received...

Above is one of the two LED replacement fittings that came in the box. The bulb fitting is made from aluminium and is quite the weight. The extra box is the part that tells the car not to indicate a fault. The box is also made from aluminium and the connector is the same type that will fit my car.

The base of the LED fitting has a fan to keep the LED's cool under operation.

Although I am reluctant to think these LED's will improve my night vision, I must do a comparison of the specification with the old halogen bulbs.

The old bulbs are at a maximum of 55 Watts each, whereas the new LED's are...wait for it...A WHOPPING 160 Watt or 30000 Lumen. That has to make a difference! The colour temperature of the LED is 6500K which should give out a nice crisp white light instead of the yellow candle bulbs that are currently installed. 

The specification and the fittings of the LED are impressive, I just have to wait until daylight tomorrow to fit them. I can't wait to see the difference.

The picture below show's the light intensity and the beam pattern of the standard 55 Watt halogen bulbs in the car at the moment...

and another picture below

I think the second picture is actually a better representation of how poor the lights are.

And another picture of the headlights when the car is fully inside the garage.

A picture of the car headlights from the front. As you can see, the yellowish/low light that the headlights produce at the minute.

Please join me when I install the new LED's tomorrow as I will show you how I installed them!

Until tomorrow, take car.
