I'm planning on changing out all the interior incandescent bulbs to white LEDs.

Anyone have a guide? I saw that sewell has a kit for $100. I'm looking to spend quite a bit less than that.

 

these are way better than just changing out the bulbs

I have always used VLeds.Com for all my LED bulb purchases. They're a bit pricy, but you get what you pay for. I would wait for the holiday sales event where they offer 15-20% off. You can probably do the whole car for under $100

 

I have the LED kits from amazon, paid like $15 for like 20 bulbs! direct replacement!

 

I've been using VLEDS for years, at least 5 years back. At that time a pair of 194 light bulbs was just $9.99. Sometimes I got it for $4.99 after coupons.

However, the price is skyrocket right now. The same pair is $25, which is extremely expensive. I counted the whole car upgrade will need:

3 pairs for dome: 3 front 3 back (194 bulb)
1 pair for footwell (194 bulb)
1 pair for front doors (194 flank)
1 pair for courtesy mirror light (194 bulb)
1 pair for make up/ sun visor mirror (194 bulb as well)
1 pair for glove box/trunk (194 bulb)
1 pair for backup light (921 bulb if I remember correctly)

7 pairs x avg $25 each = $175 before coupon/discount.

Also contacted them to ask about correct bulb size for the 2014 IS, they said should be the same as 2013 model. You can check the bulb size on sylvania.com
