2 +power source to 1LED load?

It's working fine right now but I just want to ask if it is a safe idea? I used 1n4001 diode in each power source line so that the current flow won't jump to the other power source and vice versa.IMG_20200703_155204.jpg

Yes, that should work fine

The cathodes of the diodes (end with the stripe around it) should go to the anode of your lamp. If the lamp is simply an LED it will need a resistor in series with it. Not that the maximum rated reverse voltage on a 1N4001 is 50 volts.
