Thanks for the compliment
Again, it'* nice that everything has worked out for you.
Everyone has individual preferences for test equipment. Personally, I have a Fluke multimeter. I've had if for many years and used it extensively during my years in the service industry. What you select really depends on what you need it for. In most cases, if it is for basic automotive or home troubleshooting and average $20-$40 meter from your local store will do the trick. I like analog meters for some applications and digital meters for others. For most applications, the digital multimeter is easier to use. Some are auto ranging which can also simplify things. I wouldn't spend too much if you only plan on using it occasionally. Check out the owners manual. These are easily damaged if you measure voltage or current while it is set to a resistance scale.
As for handling of bulbs, this depends on the type. You should never handle a halogen bulb with bare fingers. Oil from your skin can be transferred to the glass. These run extremely hot and the oil can ultimately cause a failure. Halogen bulbs are under pressure whereas regular incadescent bulbs have a vacuum inside. There is a greater risk of projectile glass particles if a halogen bulb bursts. Incandescent bulbs such as marker, signal, stop and reverse lights are not a concern when it comes to contact with your hands.
