## Description

From the manufacturer An excellent choice for frequent long journey and round-the-clock usage Leveraging a century of automotive lighting expertise, Bosch ensures excellent quality. Bosch brings to you the Longlife Daytime halogen bulbs, your partner for automotive lighting excellence. With a longer lifespan than standard counterparts, they ensure fewer replacements and offer good value for money. Easy to install, the Longlife Daytime is an excellent choice for anyone in need of replacement headlights. Their remarkable longevity and adaptability for both daytime and nighttime driving make the Longlife Daytime halogen bulbs a reliable lighting solution. For any driver, they are an essential component for the road, ensuring a safer and more reliable driving experience. Long-lasting Features a lifespan that is 3x longer than standard halogen lights. Adaptable Visibility is enhanced at night and during the day, promoting safer driving. Enhanced driving comfort Ideal for drivers who drive with lights on during the day. Low maintenance Reaching a lifespan of more than 1000 hours, these bulbs require fewer replacements. Never in the dark For your safety and to be compliant with the law, Bosch recommends that you always have a box of emergency backup bulbs in your vehicle in the event of failure. Gloves are your ally Handling bulbs with your fingers may reduce their lifespan. When replacing them, it is advisable to use gloves. This also helps avoid potential burns. Change your lamps in pairs If one bulb goes out, it won’t take long for the other one to stop working. For your safety and to save money on repairs, Bosch recommends changing both bulbs simultaneously. Stay bright Bulbs naturally deteriorate and diminish in intensity over time. Bosch recommends changing them every 2 years on average.

Review: Amazing - Proper, old-school bulbs that just work. No drama, no error lights, no flickering like a haunted house. Swapped them in and my indicators lit up like they’d had a motivational speech. Bright, clean, and built like Bosch actually cares about making things that last longer than my patience on the M1. Perfect little upgrade for any car that’s sick of cheap bulbs blowing every five minutes.
Review: Just what i needed - I purchased these before but only needed to replace the 1 bulb it lasted about a year then recently had both front daytime running light bulbs give out on me i'm guessing it wasn't an issue with the bulbs as both blew. so i purchased this pack (again), nice a bright bulbs again at a reasonable price. Arrived quickly, The only issue is fitting them properly. It's not an issue with the bulbs but my big clumsy hands. these are compatible with my 2014 VW T5.

## Questions & Answers

**Q: Would this fit a 2003 citreon c3? It tells me it will but the year is off.**
A: Hello, yes this bulb will fit your vehicle for rear fog light or reversing light only, this will not fit/work as a rear light/brake light for which you will need a dual filament bulb.
Hope that helps you.

**Q: Would this fit a Fiat grande punto 2007 as a running light?**
A: Sorry I don’t know. Works for Audi A6. So Fiat being Italian may not work on German cars

**Q: Does anybody know of these fit a 2013 Kia Picanto daytime running lights?**
A: Not sure. Take the bulb out and check the code on it

**Q: do they fit nissan pixo**
A: check the number on your old bulb if it has P21W it will fit
