### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Not good with LED wiring
  

*by J***E on Reviewed in the United Kingdom on 10 July 2021*

This tester is OK for incandescent lighting bulbs but I found it pretty useless for trailer side wiring when LED bulbs are installed. Needs a PP3 9V battery. Also the price is too high for what it is.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars

Ideal value for testing trailer lights

    Arrived damaged
  

*by A***L on Reviewed in the United Kingdom on 19 May 2023*

There was an Asda 9volt battery which had broken free damaging the battery cover. Sent straight back. I assumed it would come without a battery. Why Asda?
