Top_Speed1's info was very helpful for replacing my bulbs with LEDs. Unfortunately, his links to VLEDS are no longer current, so you can't just click to see exactly what he bought. However, you can find what you need based on the other details he posted. Searching by bulb number at
http://www.vleds.com/shop-bulb-numbers.html is probably easiest.
http://www.sylvania.com/en-us/appli...bulbs.aspx?year=2013&qual=&model=2151&make=18 is Sylvania's bulb listing page ('11 and '12 are the same as '13, which is the newest they have). The biggest difference I found from what Top_Speed1 posted is that the vanity lights are listed as 7065 bulbs. I bought some LEDs advertised as the "3022" base, and those festoon contacts are much bigger than what is used in my 2014's vanity lights. I was able to cram them in there, but they definitely were not made to fit the contacts. From what I can tell, the 7065 is supposed to be the "fuse" style light, with smaller ends. I'm seeing the LED versions advertised on eBay as "
T6 6641".
http://www.vleds.com/5k-white-hi-power-3-chip-2-led-vanity-sun-visor-light-bulb.html is the current link to that style. I've seen them with 1, 2, or 3 5050 LEDs on each one. While visor lights always seem rather dim, these LED replacements are very bright - maybe too bright.
There are a few different bulb numbers listed for different positions. These incandescent parts have slightly different globe sizes or wattage ratings, but they all have the same base, so "194" or "T10" LEDs will work for all of them.
3x 194 (3.78W) for the dome lights. There's one up front between the map lights and two in the backseat area.
2x 2825 (5W) for the map lights.
2x 2825 (5W) for the license plate lights.
1x 175 (8.12W) for the cargo area light.
I've had good luck with
JTECHnow LEDs for my bike and other things. You can get an 8-pack of 194 LEDs (5x5050 SMD LEDs on each unit) for under $8 shipped from the US that will cover all the lights mentioned above. The Pilot brand 194 LEDs that I saw at AutoZone for $13/pair looked identical to these, other than the color of the plastic base.
I found them to be too bright in the map lights, so I ordered a couple different styles in red to play with. The red is definitely more tolerable, though I'd prefer white (but slightly dimmer) light.
The right-angle flank LEDs (
http://www.vleds.com/5k-4-hpf.html) that Top_Speed1 listed would probably work better for the plate lights and cargo area. They would direct all the light in one direction, rather than having half shining at the back of the housing. The only issue with cheaper ones is that if they're wired up opposite of the car's connector, it's not easy to just flip them over to get the right polarity (VLEDs' units are made to work either way).
The cheap 194 LEDs in the license plate lights have started flickering after a few months. It doesn't seem to be a contact problem between the bulbs and the sockets. I'm not sure if it's due to temperature, humidity, vibration, or something else. I've been meaning to do something with them for a while. A cop followed me all the way to the edge of town last night, so I finally tossed the OEM bulbs back in for now and have ordered the VLEDS flank LEDs to replace them.
I got a directional 7W Cree 3157 bulb from JTECHnow for the reverse light. I'm not sure if it's the lens, the directionality of the LED, or something else, but it seems a bit dimmer than stock. However, I didn't back up in the dark a whole lot, so it could just be my imagination. I might do some swapping once I get my camera installed (as that will make it easier to see how well-lit it is back there). The lens on the LED itself makes for a very focused, perfectly-circular, spotlight-style beam, as opposed to a generic unidirectional LED bulb.
I haven't done anything with the turn signals (7444NA) yet. My original goal was mainly to get rid of the yellow light from the incandescent bulbs (though the reliability and efficiency don't hurt anything either).
