cheapest on the market
I recently purchased the OSRAM ULTRA LIFE P21/5W halogen signal lamp, and I must say, it's an outstanding product that exceeded my expectations in every way. Not only is it an excellent and reliable replacement for my car's signal lamp, brake light, and rear fog light, but it also comes at a price that is much more affordable than what I found at Halfords. First and foremost, the performance of this OSRAM ULTRA LIFE lamp is top-notch. The brightness and clarity of the light it emits are remarkable, providing clear signals to other drivers on the road and enhancing overall safety. Its quick response time gives me peace of mind, knowing that other motorists will be able to react promptly to my brake lights or turn signals. Durability is a significant factor for me when it comes to automotive bulbs, and the ULTRA LIFE P21/5W lamp did not disappoint. As the name suggests, these bulbs have an extended lifespan compared to standard halogen bulbs. I've been using them for months now, and they continue to function flawlessly, with no signs of dimming or failure. The installation process was hassle-free, and the double blister packaging is a neat touch, providing extra protection during transportation and storage. It also means that I have a spare bulb on hand in case one ever needs replacement, although I don't foresee needing it anytime soon due to the bulb's impressive longevity. As for the price, I couldn't be happier with the value for money that OSRAM offers. Compared to similar bulbs available at Halfords and other retailers, the ULTRA LIFE P21/5W lamp is notably cheaper without compromising on quality or performance. It's a win-win situation for me, knowing that I've saved some money without sacrificing the safety and reliability of my vehicle's lighting system. In conclusion, the OSRAM ULTRA LIFE P21/5W halogen signal lamp is an excellent choice for any car owner looking to replace their signal, brake, or rear fog light bulbs. Its exceptional performance, extended lifespan, and affordability make it a standout product. If you want a reliable and cost-effective solution for your car's lighting needs, look no further than this OSRAM lamp. I highly recommend it!

Great bulbs
Osram are great bulbs, long lasting, bright and good light color/temperature. Look good at night and are functional and easy to install depending on the car.

Easy to Fit and Affordable
I used this Osram ultra life P21/5W as a break light for my Ford. You can easily check on your driver's manual if it's compatible with your car. It shines bright and it's easy to install even if you're not a car wizard (I followed a step by step video). So far it has been great even from a durability point of view, with 5 months and counting.

Great lights
Though you practically need a mechanics qualification to change the lights on my car, somehow i managed it. Been a few months now (i keep light son 24/7 as studies show less likely to be in an accident if you do) and its lasting well and still significantly brighter than the last one halfords put in a few months earlier at considerably more cost (with me perching over their shoulder to learn how

Ford Focus Mk3 Muppet Alert
Just in case of use to anyone else - bought these for a Mk3 Ford Focus (14 plate) and they do not fit. These are dual contact and the Focus wants single contact. Local garage happened to have given my wife a spare Ring Automotive RB380 12V 21/5W which fitted and worked. Photos show the two bulbs side by side single contact on the left (fits) and dual contact on right (does not fit). Other photo of the garage provided box which seems to work. My mistake for not checking but Amazon did flag this as a fit for my car. With the right bulb replacement was a matter of minutes and no twenty quid trip to Halfords.
