Light Horse and Dark Lion

I think you mean one of these — nothing exact called "Light horse and dark lion" came up, but these have both in them:

### *1. Dare - "White Horses (Lion's Heart)"*
Has the white/light horse + lion heart together
A younger man with a lions heart
To face the brave new world
Now he can run but he can't hide
From the love she felt inside

There's a light across the horizon tonight
With her white horses by her side
And she whispers low to the skies
White horses hold him high

Brighter days 'neath the autumn sun
For the fortune he will claim
And by his heart her silver chain
And the love that still remains

She stands on that shore and it feels like rain
And the year goes so slow 'til he's home again
And she whispers low to the darkened sky
White horses hold him high
This lion heart never dies【1926237015314468890†L396-L398】【1926237015314468890†L405-L408】【1926237015314468890†L419-L423】
### *2. Iron Horse - "Dancin With The Angels"*
Light vs dark theme, lions roaring
dancing with the angels
while the lions roar
there’s a pathway of darkness
there’s a pathway of light
and they meet at the old crossroads【1926237015314468890†L92-L96】

you’ll be dancing with the angels
just like old daniel in the lion’s den
the door will be open
the feast spread out before
dancing with the angels
while the lions roar【1926237015314468890†L100-L105】
### *3. Manowar - "Black Wind, Fire And Steel"*
Black horse + lion's heart
Black Wind always follows
Where my black horse rides.
Fire's in my soul
Steel is on my side.【1926237015314468890†L367-L370】

The mystic soul and lion's heart
Brought by the talisman.【1926237015314468890†L340-L342】
### *4. Harrod and Funck - "Lion Song"*
Mentions horse and lions
These two lions that I know
As beautiful as they are strong
Sleeping in each other’s arm【1926237015314468890†L9-L11】

When you go out on your horse
And you hit a tangled course
Feel the pressure underneath【1926237015314468890†L21-L23】
