unscrew locking ring 1/4 turn. pull bulb out of reflector. unplug bulb from socket. reverse order to reinstall bulb. this is the standard way to change a 9004 etc. bulb. yours should be the same.
lumen
Should be about 850 lumens. The same brightness is produced by a 15 watt CFL.
The output of bulbs varies. A typical output of a 60W incandescent bulb is 680 lumens.
yes ,you need to change bulb.
This question is ill posed. Lumen is a unit of measure for how much light comes from the lamp Watt is a unit of measure for how much energy is used by the lamp If the question were; "Which is brighter, a 2000 lumen bulb or a 1500 lumen bulb?" then the answer would be: The 2000 lumen bulb. I think the relation ship between lumen and watt is something like: Incandecent bulbs are 15w/lumen Flourecent bulbs use 40w/lumen LED bulbs are 70w/lumen The way to show the watt and lumen relationship is usually lumens (amount of light) per watt (energy consumption). This is like gas in your car (Miles or KM per Gallon or Liter). Incandescent bulbs have a maximum luminosity of 52 lumens/watt. Fluorescent bulbs range from 46 lumens/watt (CFL) to 100 lumens/watt (T5 and T8 tubes) LED bulbs range from 29 lumens/watt (older, low efficiency) to 100+ (XCree) and they are getting better.
That bulb should be accessable from inside the trunk. Pull the carpet away from the area behind the bulb. There should be a screw out bulb holder. Just twist it and pull it and the bulb out. Replace the bulb and twist the bulb holder back into place. Re-seat the carpet.
The brightness of an LED bulb is usually measured in lumens. However, the number of lumens produced by a 2.3W LED bulb will vary depending on the specific type and model of the bulb. It is best to check the manufacturer's specifications or packaging for the lumen output of the specific bulb you are referring to.
From 550 to 750 lumens
A 50 watt incandescent bulb is about 650 lumens.
