Sure, if you don't mind them being so dim that you probably won't even see them! But it is perfectly safe.
Check fuses If you are getting power to socket, but not through it ,replace socket
Yes, as long as it has a filament for producing light for example a Tungsten Halogen Lamp, normal Incandescent or GLS lamp. If the lamp is rated at 12v it will run on either 12vac or 12vdc.
That would be a ( 12 volt battery ) in the engine compartment of a 1998 Ford Explorer
If the type of light bulb you are using was made to run on 1.5 volts, a 1.5 volt battery should be able to light up one or several of those types if they are each wired in parallel directly across the 1.5 volt battery.If the type of light bulb you are using was made to run on 0.75 volts, a 1.5 volt battery will light up two or more of those types if they are wired in pairs in series across the battery.If the type of light bulb you are using was made to run on, say, 3.0 volts, a 1.5 volt battery will not light it up very much - it may just glow dimly.If the type of light bulb you are using was made to run on any voltage higher than, let's say 5 volts - for instance a standard 120 volt household bulb - then your 1.5 volt battery will not be able to light one of those up at all.Another answerYou can wire any number of 1.5v bulbs in parallel, but for each one you add you will draw more current. Draw too much current and the battery will get hot and may explode, depending on what it is made of.How long the battery will be able to keep the light bulbs lit will depend on the size of the battery, meaning how much charge it can hold. (Its capacity in amp.hours.)
If your 1949 truck is a CHEVY or GMC and it still has the original electrical system, it would be 6 volt, negative ground. If it is a Dodge or a Ford with the oringinal electrical system it would be 6 volt, positive ground.
Yes if it is a 12 volt DC bulb.
No.
Buy Sylvania Bulbs, 7443 type 12 volt
no
yes, but it will glow less than a 12 volt one
12 volts is enough for a 12-volt 100-watt light bulb. It would not be enough for a 120-volt or 240-volt bulb.
A 13.5 volt bulb will burn less brightly but last longer.
A couple quick questions first please ... why are you using a 12 volt lamp in a 6 volt system? Have you increased the system voltage? Simply replacing a 6 volt bulb with a 12 volt bulb will cause the 12 volt bulb to burn dim ... Some systems have electrical circuits that drop (decrease) the voltage to certain units (like lights). For instance, your car is a 12 volt system (actually 14 when alternator is operating) and that 12 volts can be reduced with resistors to supply only 6 of those volts to a light ... or other device. Simply replacing with a 12 volt lamp will cause it to burn dimmer. Sorry to answer with a question but, I am just curious ...
A bulb designed for a higher voltage application than the one it's used in will not shine as brightly as it is supposed to. For instance; a 24 volt light in a 12 volt socket will be dimmer than it's designed to be.
If it is a 12 volt panel it will light a 12 volt bulb. Most likely it is not a 12 volt panel, it is some other voltage, so you then need equipment like an inverter to convert the energy to 12-volt energy.
If it is an 18 watt 12 volt bulb, then yes. But an 18 watt 120 volt bulb - then no.
Is the bulb a 1.5 volt bulb? A 3 volt bulb? A 12 volt bulb or a 120 volt bulb?Or does it have some other voltage such as 230 volts which is very common in Europe and many other countries of the world?What is the wattage of the "big light bulb"?This question cannot be answered without knowing at least the voltage and the wattage of the light bulb that is being asked about.
