in older vehicles you put a 100- 125 watt H4 bulb (with relays ) as the reflector was metal and could stand the heat
modern cars use plastic reflectors so going over 65-85 H4 would probably melt the reflectors
Leds are a better option as they produce little heat but the installation is not straight forward as they need ballasts fitted to activate properly
I would have a talk with an auto electrician that knows how to fit the led lights and what is required.
There is a plastic ring that holds the bulb in place . You need to spin the ring counter clockwise to unhook the ring from the reflector. If the battery is in the way you may have to remove it before taking out the headlight. The wire harness unplugs from the back of the bulb but may be stuck. If you try to unplug the harness before removing the bulb you might brake the retaining ring. Therefore, turn the ring, wiggle the bulb free of the reflector, then get a grip on the bulb and work the harness plug off the bulb. Now place new bulb in the reflector, put on the retaining ring and turn clockwise till it stops, plug in the bulb harness, and test the bulb by turning on high and low beam.
Hello; To change bulbs remove the cover in the trunk (pull it away) Remove the nut's/wing nuts and the assembly will come out. If you ever have to change any of bulbs that are on the deck lid you will need to remove the covering on the inside of the deck lid, remove the assembly and change the bulb.
The headlight assembly is accessed from
inside the fender well. There are two pop out plastic rivets and a
small (4mm? head) body screw that secure the fender liner to the
fender. Those need to be removed. Pull the fender liner back enough
to work your arm into the fender. Locate the wiring
to the headlight and grasp the plug. Rotate it to the left until the
bulb is free of the reflector. Pull the lamp and wiring out from
behind the fender liner. Remove the bad bulb. There is a release tab
on the plug. Insert the new bulb into the plug. DO NOT touch the bulb
glass. The oil from your skin can cause the bulb to explode when it
gets hot. Hold the plug and work the bulb and wiring back to the
original position. It is a little easier to look through the
headlight lens as you work the bulb back into the reflector. Turn the
plug to the right until it is properly seated. Replace the two pop
out rivets and the body screw.
You should replace the
headlights in pairs. I didn't and the right bulb went out in a couple
more weeks when the weather was much worse. The right bulb was more
of a pain to replace than the left, probably because I am right
handed.
