bridle darkening?

Just wondering if anyone knows any ways to darken a leather bridle? I tried neatsfoot oil and it made a little difference, but I still need it to be darker to match my other tack, please help! I got it for a gift (was on sale... not returnable) and really want to make it work. Thanks!

You can use Leather Show Dye, I had to do that to a Leather Hackamore, they only come in light.

Lederbalsam. Darkened mine :]

Hydrophane is some of the best stuff. They have a darkening oil that works well. It only darkens slightly though, so it make take a few coats. Just put on a coat or two a week until it reaches the desired color.
Hydrophane Leather Darkening Oil: Legacy Tack

I used Hydrophane Leather Dressing and it worked really well and made my bridle nice and supple. What I did was take the bridle apart and put all of the pieces in this container (minus the bit, of course) and then I poured the Hydrophane all over everything and let it all soak overnight. Then in the morning I worked the oil over each piece one last time and then I set everything out in my backyard in the sun for the entire day when I was at work. I got home, the bridle had soaked up all of the oil and was darker and nice and soft.
