Praise be to Allaah.
It is not permissible to rent these lights to anyone, because the electricity used for them does not belong to you. What you have to do is tell the owner of the house and ask his permission to let others use it, because the Prophet (blessings and peace of Allah be upon him) said: It is not permissible (to take) the property of a Muslim except with his consent. Narrated by Ahmad, 20172; classed as saheeh by al-Albaani in Saheeh al-Jaami, 7662.
And Abu Dawood (5003) narrated from Abd-Allah ibn al-Saa'ib from his father from his grandfather, that he heard the Messenger of Allah (blessings and peace of Allah be upon him) say: No one of you should take his brother's property in play or in earnest. And whoever has taken his brother's staff, let him return it. Classed as hasan by al-Albaani in Saheeh Abi Dawood.
And Ahmad (27803) narrated from Abu Humayd al-Saaidi (may Allah be pleased with him) that the Prophet (blessings and peace of Allah be upon him) said: It is not permissible for a man to take his brother's staff without his consent. That is because of the fact that the Messenger of Allah (blessings and peace of Allah be upon him) emphatically forbade one Muslim to take the property of another Muslim. Classed as saheeh by al-Albaani in al-Silsilah al-Saheehah, 5/280
It says in Subul al-Salaam (3/61): The hadeeths indicate that the property of a Muslim is haraam unless it is given willingly, even if it is small, and there is scholarly consensus to that effect. End quote.
It is no secret that the owner of the house pays money in return for what he uses of electricity. Taking electricity from him without his permission is a transgression and wrongdoing. If we add to that the fact that you are taking money from others in return for that, it comes under the heading of consuming people's wealth unlawfully.
Based on that, you have to do three things:
1. Repent to Allah, may He be exalted, from transgressing against the rights of your brother and using his property without his permission.
2. Tell him of what has happened in the past and ask him for forgiveness, and pay for electricity that you have used if he wants that.
3. Do not take electricity from him for anyone except with his permission.
We should point out that it is not permissible to organise football matches in return for payment. See the answer to question number 131652.
And Allah knows best.
