What if the developer doesn't install the property with lights?

Check the terms of the contract and communicate with the developer.

1. Check the terms of the contract: carefully check the agreement on the property to be lit in the house purchase contract to confirm whether there are clear installation terms and liabilities for breach of contract.

2. Communicate with the developer: If it is found that the developer has not installed the lighted property, you can first communicate with the developer to understand the reason and ask him to install it according to the contract.
