Hello, I am new to the electrode and I have a problem how to connect LED 12/24 V LEDs in an agricultural tractor, they are LEDs Wesem CRV1 35W. I am thinking about installing LEDs on 541 relays and I have a question: will 541 relays be suitable? 1 relay for 2 lamps to give? And how to connect them?

Yes, they will be. Yes, one relay is enough. The diagram below: You can give the lights under a separate switch, or connect under the position light switch. However, the latter solution is less functional - as it is impossible to turn off work lamps and drive only on ordinary traffic lights.

Thanks for the answer, but I have a question whether LEDs are generally sensitive to voltage drops? are relays needed for this kind of lights? I know that with halogens their lack is noticeable but I do not know how it is in the case of LEDs.

It depends how the lamp is built. As in the middle of the lamp sits the LED power supply converter then there is usually a greater tolerance for voltage drops - even at lower LED voltage will remain full brightness. However, if there is a simple power supply system, such as a resistor or some poor current source, such a lamp can be equally sensitive to voltage drops as well as the bulb - and even more.
