LED Light Bulbs are based on light-emitting diodes; the most notable advantages of LED light bulbs over conventional light bulbs are LED light bulbs last upwards of 50,000 hours. Additionally, LED light bulbs consume very little electricity. They are also shatterproof, run cool to the touch, and contain no Mercury or hazardous substances.
Even though it is connected to a 9 volt source, it is still a resistor.
Please do not try that, with new fresh batteries stream explosions sometimes result!!!!
no
The battery life (assuming it is a primary cell) is determined by the Ampere-hour drawn from it. You cannot connect a 3.5V bulb directly to a 9V battery. The bulb will fuse.
you better not. you need a 9V regulator for this, not a resistor!
They might burn but they would be very dim and the battery would last for a very short time. They are 12 volt lights therefore it will take 12 volts for them to burn at the level of brightness that they should.

No.
You can buy 9V batteries from almost any supermarket
No, it is not recommended to plug a 9V DC power source directly into a 220V outlet. Doing so can damage the device connected to the 9V source and pose a safety hazard. It is important to match the voltage requirements of the device with the power source to avoid potential damage or injury.
Yes, a 9v battery can be dangerous if mishandled or ingested, as it can cause burns or internal injuries. Ingesting a 9v battery can also lead to serious health complications or even death. It is important to handle and store batteries properly to avoid accidents.
