In a certain code language, ‘APPLY’ is coded as ‘ZTTPC’ and ‘MOUSE’ is coded as ‘QNTWD’. How will ‘LIGHTS’ be coded as in that language?

The logic followed here is as follows: All the vowels are replaced by their immediately preceding letter, as per English alphabetical order. The consonants are replaced by their fourth succeeding letter, as per English alphabetical order. A – 1= Z P + 4 = T P + 4 = T L + 4 = P Y + 4 = C Code for APPLY – ZTTPC M + 4 = Q O – 1 = N U – 1 = T S + 4 = W E – 1 = D Code for MOUSE – QNTWD L + 4 = P I – 1 = H G + 4 = K H + 4 = L T + 4 = X S + 4 = W Code for LIGHTS – PHKLXW
