Always fantastic serviced - Fitted these bulbs in a 64 plate Mini Cooper 'S' and made quite a difference, especially on full beam - See more of the road at night and I would recommend these bulbs
Advantages: Brighter more concentrated light output especially on full beam lovely crisp bright light omitted. Great for night driving in dark country lanes.
Disadvantages: No so good on dipped beam but better than the standard halogen bulbs. It may be because of the shape of the Cooper's light design?

Chose this brand over the others as I've already bought an LED bulb from them for my Astra K and it has been amazing for over a year now.
This current bulbs were for my Hyundai i10 and I'm glad I chose this brand name again.
Advantages: So far, the level of brightness has been amazing, especially on very dark back roads. They work better than the original ones. I drive with confidence knowing I can see clearly both near and afar.
I will highly recommend this bulb from this brand manufacturer.
Disadvantages: None so far

Certainly an improvement but not game changing. For me the light is a bit yellow and appears less bright than the numbers suggest. Personal opinion but i've had other bulbs that are whiter and better suit my eyes.

Definitely a step up from previous 150% Osram bulbs. Not as white as hoped - think at least 4000K would be better. Not as far reaching as hoped either. Good on full beam on country roads. So not as good as many newer cars standard bulbs buy better than 150% bulbs!
Our Reply: These bulbs are primarily designed for increased vision, not whiter light as creating whiter light will reduce the light output a little due to the added blue coating on the bulb. We do have whiter light options available, but these bulbs are for increased vision only. We are glad to hear they outperform the +150% bulbs which is what we would expect from a +200% bulb :-)

Excellent bulbs. White light with long reach particularly on the nearside. Hedges and road edges well light. FAR BETTER than the original Honda bulbs and I thought they were good. Full beam is mega but got to be careful no cars in front in the far distance and certainly need to dip prior to oncoming traffic - same as any decent driver would do. Country lanes feel 'safer' as much clearer view of hedges, wildlife, junctions and turnings. Well worth fitting especially for winter driving in dark nights.
Advantages: Clearer Vision
Disadvantages: None so far

I chose these particular bulbs as the previous Daylight 150 version were reviewed by Auto Express and were the winner in 2021.
Being a direct replacement, they were easy to fit and the difference over the standard bulb is amazing, well worth the extra cost.
The ordering process and delivery from Auto Bulbs direct was faultless and on time.
Will certainly recommend to friends and family.
Advantages: Direct replacement, easy to fit.
Significant improvement over standard bulb giving cleaner brighter light, beam covers a greater distance thereby making night time driving safer.
Disadvantages: None, I’d certainly recommend these over standard bulbs

Purchased the lights to replace the standard bulbs on a mini cooper. Very pleased with the products which were easy to fit and better than the originals. Delivery was a little slow and spoke with customer support who were excellent and were keen to help.
Advantages: range of products and customer support.
Disadvantages: Purchase a cheap random product to obtain free delivery. This product was out of stock and delayed the arrival of the bulbs I needed.

This particular bulb chsoen because of 12 month warranty compared to competitors 6 months. Compared to the manufacturers original fit the dipped beam is markedly improved (Fiat Panda Cross), but I would have preferred a higher kelvin say 4000, to get a better white. Full beam is now excellent.
Advantages: Distinct improvement in dipped and full beam brightness and distance/coverage.
Disadvantages: Light colour not as white as I had hoped.

Good H4 main beam replacement bulbs. I’d take all the dramatic %brightness stats with a pinch of salt, these are perfectly adequate filament bulbs but don’t expect Xenon or LED levels of brightness. Arrived quickly, we’ll packaged and certainly brighter than original bulbs with whiter light.
Advantages: Good value, quick delivery, good communications.
