My DIM-WIT no good half-brother gave me this binary text. Lead the way and help me show him who the B055 is.

This is an encoding of the 7-segment display.
And we simply have to map the bits to the display. So I wrote a little script to interpret each code to an ASCII 7-segment display.
pattern = [
[-1, 0, 0, 0,-1,-1,-1,-1],
[ 5,-1,-1,-1, 1,-1,-1,-1],
[ 5,-1,-1,-1, 1,-1,-1,-1],
[ 5,-1,-1,-1, 1,-1,-1,-1],
[-1, 6, 6, 6,-1,-1,-1,-1],
[ 4,-1,-1,-1, 2,-1,-1,-1],
[ 4,-1,-1,-1, 2,-1,-1,-1],
[ 4,-1,-1,-1, 2,-1,-1,-1],
[-1, 3, 3, 3,-1,-1, 7,-1]
]
ans = ['' for _ in range(len(pattern))]
with open('50.txt') as f:
codes = f.readline().strip().split('-')
for e in codes:
for line in range(len(pattern)):
for idx in pattern[line]:
if idx == -1 or e[idx] == '0':
ans[line] += ' '
else:
ans[line] += 'X'
# Uncomment to prettify
# if e == '00000000':
# print('\n'.join(ans))
# ans = ['' for _ in range(len(pattern))]
print('\n'.join(ans)) XXX
