Not that this is anything important but I thought I would share. The dash lights have always been dimmer then I liked in these model trucks and blazer/jimmy's. I have tried a few things but I found a perfect way and have been running it for over a week now. The 194 bulbs are about 2 to 3 watts each. I found out that the 3652 type bulbs are the same size but are 5 watts each. That makes the perfect difference. The heat is not any more that i have been able to tell. The auto parts stores sell these things for almost 6 bucks each. I found this place online http://www.automotive-lighting.com/mini_bulbs.asp They have the same exact bulb in 10 packs for 12.96 plus shipping. You need 5 for the dash lighting itself, one for the a/c controls, and one for your 4x4 lever. The other bulbs do not need to be changed. Hope this helps. Scott PS. The newer blazers(not sure when it started) has the bulbs soldered to the sockets. You can buy these sockets too but they are expensive. Go to the junk yard and grab a bunch. Many of the older cars and trucks used them.
