TOD lights are led's about the size of a pin head. Not worth messing with and you probably would never get them back together again. Trust me I took the entire TOD light housing apart and even thought about taking of the LED's and putting my own in, but it looked WAY too risky. I replaced all of my interior lights to blue LED's, behind the gauges is no big deal they are just normal 194's, four of them to be exact. If you get some brand of led's that are oversized you might need to drill holes in the back of the gauge cluster. MOst will be fine. The white reverse glow gauges are nice as well, I have those in too. The other bulbs in the interior in order to be replaced with led's like I did have to each be custom fabricated. Because the "bulbs" you are replacing are grain of wheat or rice bulbs, because they are that small. If you are interesting in doing this the hardest one to convert is the power and winter buttons below the shifter on the center. Take those apart carefully to see the worst of it. If you really want to do this trace the power wire back and put in line resistors directly on power wire right before it gets into the housing on each individual light for the new led's (so as to avoid craming the resistors into the housing with the new led). It is quite a process took me two days with the interior completely tore apart, but it was worth the time, but I am talking custom led install for every single bulb. If you have any questions feel free, I am sure I missed something or called something by the wrong name. I have tons of pics of the install but my roommate has not sent them to me yet, I saved them on his computer right before my computer bit the dust.
