im sure you can take your dash out and find all the screws that hold in the gauge cluster. I havent tried in a Jimmy before but im sure you can do it. Its true that an LED is more narrowly focused, but in most gauge clusters, the light shines into a piece of plastic which disperses the light evenly. Pull it out first and check. What else you may want to do is test those LEDs somewhere else. I got some color changing LEDs from autozone, and they burn out quick. Now im glad I didnt do all my guages in them. I used bulbs for my guages, they were fitted for size 194 bulbs, and I put the green bulbs in, which give it kind of a glow rather than a lit up look.
