Change Oil Light

[LordLang]

I have 10,000 miles on my H3. I have changed the oil twice, once at 4k and another at 8500. Neither of these times the change oil light came on, but i had it changed anyways. Now after only 1500 miles since the last change the change oil light has come on. I checked the oil and it reads full, as well as looks very clean. Any ideas on why this would happen? does it really need changed or do i just need to reset the light? and if so, how do i do that? thanks for the help!
