I just bought a pack of Westinghouse solar lawn lights and the lights are excessively dim at night. I know they are supposed to be brighter. They are in very dark places at night that get great sunlight during the day, and it appears all batteries are seated normally. What is wrong with them?

Do you have the dash light dimmer control turned dwon to dim?

photo cell is bad it detects when the sun goes down and connects the circuit

dear,

There is the issue with the wattage of bulb you have got for the vehcicle.

And also due to a new bulb it shines brighter then the old one.

get the old one also repaced to get the equal brightness

thanx

For first time use solar light needs to charge in full sunlight for 8-12 hours with the switch in the "ON" position to allow the rechargeable battery to reach maximum capacity.
There is also a protective film on the solar panel that needs to be removed.
After doing that, fully charging the battery with the switch in the "ON" position, then if the light does not turn on, remove the 4 screws from the solar cell assembly, remove the battery, wipe both ends and reinstall battery. Make sure the battery is making secure contact with the terminals. I had a new one and the battery was loose inside, making the light go on and off. I reseated the battery and all is well.
However you should not have to replace the battery or the unit, it should still be under warranty if you just bought it. Westinghouse guarantees this unit for one year.

I would counsel you to just take the unit back for exchange or refund, as the warranty has an exclusion clause and one of the exclusions is if the unit has been opened. Opening the unit might invalidate the warranty.

check that the illum (usually orange)wire is not incorrectly hooked up to acc or perm power as it dims the display for night driving (supposed to be hooked up to your headlight parker switch.)

The light will only stay on as long as the battery lasts. My guess is that will not last all night. What you can do is buy a light sensor switch (or even a light sensor socket adaptor is available to save you from having to wire it in) to keep a light on during the night. You can use a CFL or even an LED lamp to save electricity, but it is unlikely that a solar-charged cell will power even one of thes all night long.

Most of the solar lights use a stadard 1.2 volt 850 mh nicad rechargable AA size battery and you can get them at your local Home Depot store. You also might try to clean the solar cell on the light they seem to get a film over them that stops some sun light from reaching the solar cell.

Try to adjust dash lights brighter. FOr some reason the radio blacks out even when the lights are dimmed a bit. Try turning the dash lights a bit brighter and see if you can see the radio. HAve a great day.

Put a small piece of black tape over half the sensor. This will make it more sensitive to light conditions.

It's supposed to. The console is brighter during the day so that you can see it. At night, that same level of intensity is too bright. When you turn them on during the day, the car doesn't know whether it's day or night, so they get dimmer.
