When I tried to fit the DE3021 bulb into the trunk light fixture, the diameter of the bulb ends were too large. I tried making it squeeze in and it broke my fixture. The DE3021 bulb has pointy ends, the burned out lamp looked exactly like a small glass fuse. I am also looking for a replacement lamp. Although I may just go find some aftermarket "universal" light and put up 2 of them in the trunk for better lighting (original was a bit dim).
where can you get the same bulb that originally came in the trunk light? When I google it it comes up as a DE3021, but that does not even look right and it sounds like it does not fit. Does anyone know the number of the OEM bulb?
I took the bulb to a parts place, and the guy matched it up....the numbers don't matter, as long as it fits.
it does matter when two parts stores do not have a bulb that will fit. Most places think that it's a fuse. That's why knowing a number would be helpful.
I do not know how he matched it up other than we walked over the bulb section, and he handed me the right bulb....Frankly, it was a few months back, so I do not know the number. I don't want to mess taking the thing out.....sorry.
I think he should be able to order a match if they don't stock it.....otherwise call the dealership.
Just replaced my trunk bulb last night for my 1998 Avalon. I got it at the dealership. I couldn't tell you the part number or the price because the parts guy didn't charge me for it. As soon as I told him it looked like a fuse he knew exactly what it was. They also use them in the vanity mirrors. Good luck!
I have been looking and looking and looking for a trunk light for my '98 Avalon as well and have had no luck. I've not found the DE3021 bulb that it says it requires and based on posts here, they don't fit. Don't know how it is so difficult to find a bulb.

i bought a DE3021 bulb from the sylvania selection at autozone. DB is right, it doesn't fit. but since i was in it for 5 bucks i made it fit. heres how:
1) pop off the lens
2) on the passenger side of the bulb holder there is a little metal spring tab that holds it into the body. push it towards the drivers side and swing the holder down.
3) the wires connect to the holder thru a plug. pull the plug to free up the bulb holder assy.
4) it is easy to see that the DE3021 almost fits, but its too short and a little fat. notice that the clip farthest from the plug, the one attached to the little mirror, is the one to modify. slide that whole contact towards the plug and remove it from the plastic part.
5) use long nose pliers. bend the clip up 90° to grab the bulb point by the sides. then bend what was the tab that clicked into the holder 90° to make a "lid" for the little box you just made.
6) reinstall the contact into the plastic piece.
7) stick one of the bulbs points into the little box you made, swing the other end into its contact. bend it a little if its too tight.
8) put everything back the way it came out. if it doesn't work, check the 7.5A fuse in the big fuse box under the hood.
seems like a lot of work for a little bulb, but it only takes 5 or 10 minutes. note that you can't bend the metal contacts a bunch of times, they will fatigue and break. try to get it on the first go. cheers!
Anyone looking to replace the trunk light bulb on a 1998 Toyota Avalon will waste their time going to an auto parts store or trying to look up the number of a generic replacement bulb via the internet. The part number you will get from either is DE3021. That bulb is incorrect and looks nothing like the original bulb. It is 1/4 inch short and too large in diameter. On top of that, it has pointed ends. The original bulb is 1-1/8 inch long, is 7/32 of an inch in diameter, and has flat ends. In other words, it looks exactly like a fuse. The only way I know how to get the correct replacement is by getting one from a Toyota dealership or by ordering a Toyota replacement bulb online. The Toyota part number for the trunk bulb is 9098114009. It is around $4.00 at a dealership.
