    I’m wondering what the difference between the 15A H-LP LO and the 10A H-LP LH-LO and RH-LO is. I’m trying to add a circuit. I know the 15A is head lamp low (correct me if I’m wrong) and the 10A is head lamp left hand low and right hand low (also correct me if I’m wrong). 7BD1995E-F6C3-40D0-A4F5-1243CDE6410C.jpg
    I removed one of the 10A fuses and one of the low beams didn’t work but what does the 15A fuse do?

    Soooo if what I'm understanding is correct, this would mean 15A powers both 10As?

    I put a raptor light add-a-fuse in to bottom 10A fuse marked in the OP's picture of the fuse legend.....and now the left headlight doesn't work...... See my post from yesterday.

    Answers greatly appreciated pls :(

    For my sr, I tested the 15 amp fuse by adding a circuit and I have constant power so it was a no go for me.

    For the add a fuse circuit, the bottom one goes for the exiting fuse and the top is for the additional circuit. Do both work?

    You talking about the 10As? I only tried the bottom. I didn't try the top one if that's what you are asking.
