I have a 2007 tundra I just changed all four speed sensors the lights went out on my dash I was able to go from four high to four low back to two wheel drive just sitting as soon as I took it down the road I hit about 25-30 mph and all my lights came back on having just replaced all four speed sensors what's my next move or what others problems might it be

What lights went out on your dash? Like as in check engine light or TPMS light? If you mean check engine light there's no point asking anyone what the problem is because all that means is you've thrown a code and it could be any one of a million codes. Go to your local auto parts store, get the code read, come back on here and paste that number into the search box you can see just above your thread. Then read through existing threads on whatever code you might have.

The VSC traction control light came back on as well as the 4hi and 4lo started to blink again but they were off after I changed my speed sensors but came back on after I started driving it again

Have you taken it anywhere to see if there are any codes? I have never heard of anyone needing to change all 4 speed sensors. Maybe one from getting damaged but never all of them. Did someone tell you they needed to be replaced?

Yeah I had it hooked up to a reader a few weeks ago and it said 3 out of 4 speed sensors were bad so I just changed them all to be on the safe side

So what was the code that came up? Search the code number on this site to see what others have done to fix their problems. I would be willing to bet replacing the speed sensors is not the fix.
