The interior trunk light uses a really small instrument panel light bulb and is really dim. I bought a couple of the brightest T5 (74) LED replacements I could find on eBay, and they do not fit in the socket. The socket for the glass bulb is way too wide for the LED circuit board to make contact.

Recommendations? Thanks.

Be EXTREMELY careful with this; if you decide to do it then give careful consideration to pulling the deck in the passenger compartment so you can get to the wiring and installing a small-value inline fuse in the positive side of the feedwire.

Several people have reporting damaging the rear BCM via a momentary short on this circuit; it apparently is insufficiently protected against this risk internally and the fuse for the BCM will not blow first. I have a pair of LED strip-lights mounted up high and forward in the trunk (invisible from the outside but they illuminate the entire trunk when on) and I took great care to wire loom everything AND install secondary fuse protection in the feed for exactly this reason.

Thanks for the warning. I have already blown the 15A "Room" fuse changing out dome lights and the car would not start, unlock or anything.

I am very inexperienced with any wiring changes, plus I want to be able to get the car back to stock before the lease is up. A single LED change would be ideal, but obviously my 3 LED T-5 (74) bulb does not fit the current socket, just too narrow.

I just use a bright LED that I had bought a while ago. It's not bright bright as you might want it to be, but it was way better than stock and looks nice too.

Use the search. This was on the first page of results - has everything you need: http://forum.mazda6club.com/electrical/281873-led-trunk-light-swap-under-60-seconds-7.html
What an awesome forum!

Based on this, I was able to purchase from VLED, an 8 inch LED strip, which has double stick 3M foam tape, with a 74 base, and it works great. Really bright and useful, better than anything I have ever had before for trunk lights.

The photos are crap, but you can see the reflection of the individual LEDs on the lens flare...

I just installed the light strip from VLEDs into my 6.

Previously, I just had a replacement LED. It was brighter than stock, but LED strip is a much better improvement.

Easy and great way to get more light in the trunk. I set my strip deeper into the trunk.

Could someone elaborate why I can't just do an LED swap with a compatible bulb? I don't know anything about fuses or wiring, I figured I could just pop one in the trunk and be okay.

Bit of a thread update here. The trunk light in these cars is abysmal. Clearly something had to be cut from the design budget and trunk lighting was it, haha.

To improve it I started by replacing the 74 bulb with a high output LED 74 bulb from Superbrightleds. The light was certainly bright, but it just didn't put out enough and still had a severe lack of coverage. Next step was to source a trunk light kit from Diode Dynamics with a 20" LED light strip: https://www.diodedynamics.com/store/catalog/product/view/id/12589/s/2003-2013-mazda-6-sedan-trunk-light-led/category/568/#!prettyPhoto

Installation was super easy, just plug in the 74 adapter and attach to the LED light strip. The strip has has 30 SMDs, a weatherproof seal and is self-adhesive. Let's just say this is the kind of lighting every trunk needs. I don't have a pic yet, but it is literally night and day difference. It is expensive at $22 shipped, but the light output and coverage make it worth it imo.

Thanks for the tips, finally I've hard wired a 50 cm strip today with a 0.25A fuse, so far so good.
