I used a Dremel, and cut all along the seam where the two halves come together. But man, what are your plans, to put a clear in there or just take out the orange lense??? Cuz i had to make that Clear lense using one for a '94-'97 s-10. It wasnt just like an easy swap, it involved some thinking and some cutting with the dremel. So good luck!!! And when re sealing the headlights back together, be sure to use a clear glue, i made the mistake of using a tan colored glue and if you look close you can see it in person. I have also heard of people maybe using a heatgun to soften the glue to pull it apart, i stayed away from that cuz i didnt know if it would melt the headlight!!
