These LEDs light up very well and 360 degrees as shown, but are sensitive to residual currents while some considerably cheaper Chinese models are not. In summary, these LEDs flash with low intensity on my vehicle when off because of these residual currents present in the circuit. They are not adapted to automotive use clearly, despite what suggests Philips ... Ditto on another vehicle (tested at the front and rear ceiling). This product is not recommended due to the lack of added value compared to a low-end product, which for once works better.
