is there any way to split my headlights and reseal them?

 

yes there is. Use a heat gun or an oven. I used an oven when I did a black-housing DIY on my headlights (98 civic ex). Real easy and straightforward. Look up a DIY on blackhousing headlights and you'll find your answers

 

Preheat your oven to 200, then turn it off and set the headlights in there for about 5-10 min. Take them out the glue should be warm and start to pry them apart. Mine came right apart, when you are ready to put them back together do the same thing I added some silicone for an added seal.

You doing a retrofit?

Edit: ^ He beat me.
