I was bored today so I decided to see if I could put high beam bulbs in the low beams. Well it can be done. Im not sure how much more light I will get but every little bit helps. If anyone is interested, heres a quick guide.
Things you will need:
2 extra high beam (9005) plugs, and bulbs
a thin screwdriver, i used a dentists pick
a file or a grinder
optional : 2 thick o-rings
total time taken : less than 20 minutes
reasons why you cant put a high beam bulb in from factory:
1. there are 3 tabs that hold the bulb into the headlight casing. The low beam and high beam have a slightly differant pattern so you cant switch them.
2. The plugs in the car are matched to the bulbs by little tabs also, (two tabs on a high beam and 1 tab on the low)
3. also, the low beam bulb has a larger diameter hole then the high beam, so you can not put a low into the high socket, but a high fits in the low, which works out rather well.
step 1 : unplug the low beam headlight, and remove bulb
step 2 : take off that blue clip off the base of the plug
step 3 : the plug has 2 contacts. And next to each contact there is a tiny hole that contains a little clip that holds the contact in the plastic plug. stick the screwdriver into the little hole and push in towards the contact, a little clip will release allowing you to slide the contact out of the plastic plug. Do the same thing to the extra plug too.
step 4 : the tabs on the contacts will now be pressed in and will not clip into the plug anymore so you must carefully bend the tabs outwards again. Then slide on the high beam plug onto the low beam wires of the car.
step 5 : repeat for the opposite side.
step 6 : the high beam bulbs will not directly fit into the low beam sockets, so look at a high and a low bulb side by side from the front, youll see that the top tab on the high beam bulb is too far to the left. So take your file and cut the left 50% of the tab off. I used a bench grinder, made it very easy. And now the bulb will fit.
The high beam bulb has a smaller diameter socket than the low beam, so the light will have a sloppy fit in the headlight assembly. It will stay in, but it might not be 100% sealed from water, although its probably not a big deal. but f it bothers you...
step 7 : There is a thin o-ring that is on the bulb itself to seal it. I replaced that o-ring with a thicker one of the same diameter. Then apply some petroleum jelly or other lubricant to the o-ring and the high beam bulb slides snugly into the low beam socket, give it a twist, plug it in, and there you go. 65 watt low beams.
Sorry I dont have pics, but I just did this on the spur of the moment, and my hands are stil freezing from the unheated garage
The bulbs seem a bit brighter, so Ill have to take it for a drive and see what happens. The benefits I can think of would be that its brighter obviously but It still uses the low beam light pattern so it will not blind oncoming drivers. Once I modify my lights so I can put all 4 headlamps on, then this mod might now be very imnportant, but It took me about 15 minutes to do the first one, and 5 to do the other. It was easy and i figured why not? Good luck!
