2.11. Does the progressive on/off of exterior lamps on certain vehicles remain after installing LEDs?
Philips LED Retrofit range has been designed to perfectly replace the current light setup that is in the car. This
meaning that the progressive shutting on or off functions will continue to function after LED installation.
2.12. How does the beam geometry fit in comparison with a normal H4/H8/H11?
Each LED within the Philips range has been designed based on halogen/conventional bulb, following the
specification of each certification to ensure a reliable product for the drivers and for the others while driving. The
geometry of the headlighting follows scrupulously the one they are replacing.
2.13. On the driver box of the LED lamp it says: “Caution: Do not touch – Hot surface”. How hot will this
become? Is it getting this hot that it can damage cables or any other car parts under the hood?
We strongly recommend that the driver box is always attached safely with plastic ties provided to avoid to move
while driving and that the box is attached on a metal part in case it gets hot.
3. During installation
3.1. After installing an LED light, would I get an error message on the dashboard?
The LEDs have a wattage (lower power consumption) lower than conventional lights.
Some cars are equipped with light detection system to warn the driver that one of the light has failed. Meaning the
system sends electric impulses in the electrical system to check the functioning of lights. Hence when the systems
checks, the power emissions are too low to be detected.
In such cases, we have developed a CANbus adapter which converts the power and avoids any error message.
3.2. What do happen if the blinkers fail?
If the blinkers fail but not the CANbus adapter, the blinking will still be normal (the CANbus adapter will still draw
enough energy for the blinking) but the LED won’t work anymore. In this case a visual check is necessary to detect if
the lamp is still functioning.
3.3. How do I replace the incandescent bulb with a LED bulb? Is it difficult?
The entire Philips LED Retrofit range is a retrofit of halogen and conventional bulb, making it easy to replace
without any modification needed to the car. Just need to follow the guidance on or in the package, and making sure
prior to purchase there is enough space into the bulb housing.
3.4. The LED does not light up after installation. How can I resolve this issue?
If your Philips LED Retrofit doesn't light up, it’s likely that you need to "reverse the polarity" by flipping the LED.
Philips LED Retrofit bulbs work like batteries with a positive and negative polarity. In case the Philips LED Retrofit
does not light up, simply remove the LED, flip direction and reinstall as per explanation and illustration below:
1. Remove the Philips LED Retrofit from the socket
2. Flip the Philips LED Retrofit
3. Insert Philips LED Retrofit back into the socket.
