OSRAMULTRA LIFE P21W halogen signal lamp, brake light, rear fog light, 7506ULT-02B, 12 V passenger car, double blister (2 units)

I find it a bit odd that when I click 5 stars, Amazon states 'I love it', but what can I say? I'm not willing to declare my undying love, but as bulbs for the brake lights and reverse lights of my Smax they are great. Excellent brightness. As for how long they last, who knows? I've bought cheap bulbs that last years and expensive bulbs that pop when you look at them. At this price, I'm not complaining.The only thing dim about these bulbs, is the listing referring to 'break' lights.

I can’t comment on the longevity of the bulb as I’ve only just fit it. I will update the review as necessary if they don’t last.For anybody wondering, or sifting through the reviews wondering if it fits a Golf MK5 2004 model, IT DOES!I only mention this as I was concerned it wouldn’t be the right bulb.Changing the bulb itself is easy, the rear lamp is only held in with two plastic 10mm bolts. Using a socket they come off easily. Once off, simply unhook the power connector with a flat head screwdriver and the lamp pops right out. Then remove the inner plastic bulb holder with the three plastic tabs holding it in place.Simply push the bulb down and unscrew it, and replace it with the OSRAM Ultra Life bulb.Reverse the steps and wallah! You’re done!

Just what I expected

This is way better value than buying the bulb at a garage parts department. For one thing it is a quality make, plus you get TWO in a pack.At £4.25 for a pack of two you really can't beat this.

These Ultralife bulbs do have a great lifespan. I have a pair of headlight bulbs in my car which have been installed for about 10 years. Although not as bright as some they are perfectly adequate.

seemed like a good product but blew fairly quickly. Can't say for sure whether it's the product or our oven but the last bulb survivied for well over a year....

Good bulbs - they work and what more do you want? The funny story is that when I went to change the bulb, I found the old bulbs were fine, they just werent working because the light clusters were full of rainwater!Only misses out on a 5 star rating because the rear light is a different bulb on my Golf MK4 - Amazon's fault really!

As bulbs go there's not at lot to write about, they fit and more importantly work when you need them too, I suppose life expectancy is the key and I can't answer that except to say they still are working
