Question about Cars & Trucks
Technically, no as long as there isn't any power going to the headlamps there is not need to disconnect the battery cable. BUT any operator's manual will tell you ALWAYS disconnect the positive cable from the battery (or disconnect power source) when doing any sort of work on anything that has power, because you never know. If you remove the negative - you risk still grounding to the chassis if you place the cable loosely inside the engine compartment.

Turn off the engine. Pop the hood and secure it open. Disconnect the battery cables from the battery by grasping the cable and pulling it straight off of the positive and negative battery terminals.
Position yourself in front of the headlight you wish to repair. Look behind the headlight assembly to find the wiring harness for the headlight assembly. Lift the locking tab, grab the wiring harness and pull the wiring directly away from the assembly.
Grab the old headlight bulb, twist it counterclockwise and pull it out of the headlight assembly. Replace it with a new bulb and secure it by turning it clockwise.
