What's different
The l in light ends with a quick release: the tongue tip drops from the ridge behind the teeth, and the vowel is there at once. The r in right touches nothing, so it melts into the vowel slowly, and the start of the word seems to rise.
After that, both words share the same "ai" glide and the same final t, which American voices often cut short with a catch in the throat. Everything you need is in the first tenth of a second, so replay the start of each word, and switch to Slow if it helps.
