First off, mods if you want to turn this into a DIY and place in appropriate forum go ahead and edit as necessary if need be. I figure it would get most visibility in here for now. This is not about replacing all the plug and play 194 bulbs throughout the interior. This is a how-to for the factory installed yellow LED map lights.
Be warned, if you are not familiar with soldering or do not have a very steady hand do not attempt this. Overall it's an easy job, but when it comes time to connect the new LEDs it does require soldering connections onto a very small and fragile ribbon cable. I do all my mods so that if wanted I can put back to stock without permanently damaging or changing anything factory. This applies to this mod although I don't see why I ever would.
I am very picky with my mods and absolutely did not want that hyper white or cool blue 6000k look. I wanted pure white, or as the bulbs are called "natural white". These bulbs match the color and output brightness of a new car coming OEM with LED interior lights as closely as possible. You won't find a better match if you're an OEM kinda guy like myself.
These are the bulbs which matched my natural white superbrightled 194 bulbs. They have double sided tape on one side and are pre-wired making them perfect for this job. You need 2 of them: https://www.superbrightleds.com/more...ent-light/639/
These are the matching 194 bulbs I bought. You need 8 of them: https://www.superbrightleds.com/more...ofit-car/1127/
Here are some basic install instructions along with pictures. The results are absolutely perfect! Color and output couldn't be better and could pass as a 100% OEM interior light setup.
-remove console. No tools needed it's clips only. Start by working your fingers in a gap on the front side closest to the windshield and work your way around. It's in there good, but it won't break. Disconnect the wire harness and remove.
-remove the 12 T10 torx screws. Then the rest just all comes apart with plastic clips.
-remove the blue circuit board. There are four black clips holding it in place. Do not pull far away because there is a ribbon cable that you need to detach first.
-on the side, pull out the white tabs for the ribbon cable and remove that.
-remove all three LED boards. Again, just tabs holding them in. Two side boards and the center ambient light LED.
-remove black tape over soldered connections on each side LED to expose the solder joints.
-carefully heat them up and gently disconnect the ribbon cable.
-now you will rotate the LED board over. You will eventually reattach it so the original LED faces upward. This is so you can use the original board as a mount for the new LED.
-attach the new LED using the double sided tape. Be sure it's perfectly centered opposite side of the original bulb for correct focus through lens.
-now the tricky part. Solder the new bulb wire leads to the ribbon cable. I'm not sure if it's polarity sensitive, but both bulbs worked first time for me. Then using whatever you like cover those new connections so they don't flex or move. I like using hot glue gun. Basically cover that entire connection so it's now stiff and sealed.
-now the rest is fairly easy and just involves putting everything back together and cleaning up and placing the wires in good spots. These particular LEDs from superbrightleds have a ribbon cable and heat shrink so there will be excess you need to find a spot for. Mine are actually outside the circuit board housing as I couldn't get it to close with those in there. See pics.
-reinstall to ensure proper operation.
Here is the original LED map light on compared to my new natural white 194 bulbs. This is what it will look like unless you do this mod. Not terrible, but definitely not the prettiest when both are on.
