Meyer Headlight Adapter. This is the adapter included in 07108. It includes an additional module to work with the vehicle Daytime Running Lights (DRL). The DRL are a source of many light problems on these older vehicles, it is best to leave that part alone. Blown bulbs, melted sockets, overheated wires. These can all cause problems with the plow lights IF you choose to install the complete 07108 Kit. Use these 07108 Adapters instead, and leave the DRL alone. Install Instructions for 07108 so you can see what it entails IF you wanted to install the 07108 instead of these adapters alone. Again, we DO NOT recommend installing the 07108, you have been warned.
