For what it's worth, the bulb I took out says V2. And I googled it and it's a T5 bulb.
But basically, find a LED bulb that isn't too tall, the OEM bulb is short.
Also, on the back there must be flat with a place to turn a philips/screwdriver clockwise to lock it in place.
The Neo bulb has that, while the other #74 bulbs don't.
Thanks for posting all of this, is this the correct LED bulb for an 03 FX...
