The focus thereby is on high quality and a long product life. This helps to keep people mobile all over the world. For more than 130 years, Bosch has pursued the goal of offering intelligent and reliable solutions to make life a little bit easier every day. Drive with peace of mind PY21W type bulbs are used as indicator lights in untinted glass optics. They have an important role on the road to show your intentions on the road and reduce the risk of accidents on the road. Bosch offers 3 different ranges to meet everyone's needs. Pure Light: simply original quality Magic Effect: a bulb almost invisible in the optics and which turns orange when it lights up LED Retrofit: LED technology for highly efficient lighting and extended life Pure Light The Pure Light range from Bosch corresponds to the original quality and ensures an excellent value. Magic Effect Opt for a modern and timeless look with the Magic Effect lamp. Thanks to its special coating, the PY21W Magic Effect signal lamp is almost invisible behind a transparent headlight glass when switched off. It turns orange only when in operation. This brings a more modern design to your vehicle. LED Retrofit The Bosch LED Retrofit range is intended for drivers concerned about the look of their vehicle and looking for better comfort. Retrofit LEDs provide modern and elegant efficient lighting. In addition, LED lamps provide a longevity of more than 4000 hours! Once installed, you can forget about them. Lamps not ECE approved Always have spare lamps It is strongly recommended to equip yourself with an emergency box or spare lamps in order to always have the right lamp at hand in case of failure of one of them. This ensures safety and compliance with legislation. Respect basic precautions Touching the glass of the bulb with your fingers may shorten its life. When replacing the bulb, use gloves or a soft cloth to handle the bulb. Be careful of the risk of burns if you change a bulb that has just worked. The gloves will be your ally Remember to change your lamps in pairs Since the lifespan of two identical lamps is extremely similar, it will not take long for your second lamp to stop working. Your safety will be compromised. Whether you change your lamps yourself or by a professional, it is more convenient and economical to change both lamps at the same time.
