just received my led rear lights and the resistor 25w 15ohm is connected to the lights wiring but is just floating amongst the wires is this ok?? i thought it should have been glued to the back of the light. I've called the company and they say its fine how it is and the resistor will not melt any of the wires touching it. Help is this wrong

Remember these get hot, think thermal event on my last sport I fitted / glued) 50 ohms resistors with heatsink. In Spain - 2018 F Pace - Frightened away from the Sports due to crank failures
Gone - A couple of RRS, A couple of Disco's. However thinking of another Sport.
