1156 bulbs are single filament bulbs – This means the bottom has one positive connection and the metal body is the ground (-)
1156 bulbs are dual filament bulbs – This means the bottom has two positive connections and the metal body is the ground (-)
When replacing your festoon LED bulbs with LED version, depending on the LED bulb you use, it may have a metal body. You must ensure the body doesn’t touch and create a circuit between the ground and positive as circled. This would blow your fuse. You can ensure this doesn’t happen by putting some electrical tape on the area where the LED bulb may contact the terminals.
Adding LED to your interior can be very easy and beneficial on multiple aspects. Besides more light output, you will get a more comfortable light and less heat. You also reduce the risk of draining your battery while leaving your doors or trunk open by accident.
Some cheaper HID kits may cause vibration or flicker. The solution can be into a capacitor or problem eliminator plug that stabilizes the ballast voltage. Some cars have more issues than others because of CANBUS systems.
HID lights are also far more efficient because the electrical current is only the catalyst for the gas to discharge its light particles, not the primary source of heat and light. The ballast regulates a constant flow of power only to keep the gas molecules excited, while a standard light requires a constant intense electrical current to keep the filament hot.
AC is an alternating current (the amount of electrons) that flows in both directions and DC is direct current that flows in only one direction; the product that is flowing being electrons.
DC electrode wear is from one electrode due to one-way current flow whereas in AC, electrode wear is more even due to two-way flow.
There is no way to tell if a ballast is as AC or DC by looking at it without opening the case.
9012 bulbs come on some vehicles and before now were not available in HID socket size. 9012 is very similar to a 9006 bulb but with minor difference in the tabs.
The plug that feeds power to your HID ballast can be inserted two ways. If you insert it the wrong way (even if it looks correct) this will result in non-functioning ballast. Some vehicles are wired differently from the factory than others.
