by:

just received my lights for my boat trailer yesterday and everything works great lights seem well made and very easy to install. Lights were well packed and shipping was fast very satisfied with the purchase. What is best of all is the customer service you dont find service like the folks at etrailer so hats off to George and the rest of the crew there at etrailer.

I bought replacement Wesbar tail lights for my boat trailer. I think your website is excellent (informational and no doubt what replacement lights I needed), shipping was fast, everything fine.

The tail light still works like a charm but doesnt help me catch fish!



by:

I ordered bulbs and a lens for my trailer because you never know when you're going to need them. The prices were very reasonable and the they shipped within two days. Great service and price and if I need something for my trailers, I'll be back.



by:

Fast efficient delivery!



by:

I have a 2019 Dodge Ram with a trailer hitch and trailer wiring receptacle
that did not fit into the plug in receptacle.
For about x.xx I purchased a 7 blade adapter from [online store] to fit into the hitch brake plug.
I like this product very much and feel much safer with the extra brake light that works exactly like advertised.
Very happy and I could not beat the price.



by:

Correct product delivered as promised at competitive price will use your service again



by:

I've bought a few items from etrailer. Each item is of great quality and a fair price. Delivery of all items has always been timely and never a fouled up order. Great people to deal with and excellent quality of all products.

Still good



by:

Speedy delivery - they arrived before I've been able to use them - so my 4 star rating is reflective of this review being incomplete. All products in my order look to be intact and in new condition so I expect they will work well when I finally get around to mounting them on my utility trailer.



by:

Own a Yukon camper trailer from the 1980s and was happy to be able to order and receive exterior lamp bulbs without delay. In fact, I received my order 2 days sooner than I'd expected.



by:

Just picked up a couple of utility trailer lights..etrailer was GREAT to deal with...
Instructional/comprehensive videos and many Q&A's pertaining to my purchase were provided which made my install a snap! Good folks!
Thank You etrailer

  • Replacement Bulb for Wesbar Low Profile Trailer Tail Lights 403026 and 403076
    It sounds like you're looking for the replacement bulbs only for the Wesbar Low Profile Trailer Tail Lights # 403076 and # 403026. The replacement bulbs for these lights are the Replacement Light Bulb 1157 # A1157B. Since those lights are submersible and will have a seal on the inside of them, you'll want to be careful when removing and re-installing the lens cover when replacing the bulb to make sure there is no damage done in the process.

  • Changing Incandescent Light Bult of Pilot Automotive Light Up Hitch Cover
    From your picture I'm guessing you're referring to a Pilot Automotive hitch cover light like part # CR-007D. If so and it's a an incandescent light it can be changed. You remove the care of the hitch cover with flat head screw driver. There's a slow along the bottom in the seam between the lens and the houseing where the screwdrivers fits into to pry the lens off. I've linked a video that points out the location to insert the screwdriver although it doesn't demonstrate the entire process...

  • Availability of Replacement Capsules for Wesbar Trailer Lights
    Some Wesbar lights have a the sealed type of capsule, and they are not meant to be opened. Instead, you would need to replace the whole capsule. The good news is that Wesbar offers replacements, depending on the model number, that can be easily opened to change worn parts, in addition to the sealed type. If you have a Wesbar Submersible Low Profile Light # 403026 and/or # 403076, the bulbs can be replaced by removing the clear capsule inside the light. If you want to swap it out for the...

  • Should I Replace the Bulb on the Wesbar Rectangular Low Profile Trailer Tail Light or Upgrade to LED
    The Wesbar Low Profile Trailer Tail Light part # 403026 that you referenced uses an 1157 type bulb like part # A1157B. If you have power to light but still not illumination then the bulb is likely bad and needs to be replaced. If you instead want to upgrade to LED's then you can use the Optronics LED Combination Trailer Tail Lights part # TLL160RK which will be great replacements for the Wesbar Low Profile Trailer Tail Light. The LED's when compared to incandescent lights will draw less...

  • Tail Light on Trailer Not Working After Installing New Bulb
    If all of the other lights on your trailer are working correctly except the new 1157 bulb that you installed, like part # A1157B, then either the wiring to your light housing is bad, or the housing itself is bad. Check the wiring for the housing to make sure that it is not corroded, bent, damaged, or exposed, and also make sure that the ground is securely connected to a clean, bare metal surface. If all of that looks good then the housing is probably bad and needs to be replaced. I...

  • Roadmaster Replacement Lights RM-300220-20 and RM-300220-40 Bulb Types
    The bulb type that the Roadmaster replacement light # RM-300220-20 uses as a replacement is the 194 which we have as the part # A194B. The replacement light # RM-300220-40 uses a 1157 like # A1157B for the stop/tail and then a 1156 like the # DI85VR which is an LED for the turn signal.

  • Replacement Light Bulbs for 2008 Forest River Flagstaff MAC 228
    We do have the Replacement Light Bulb # 1157 # A1157B that you're looking for, but we do not have a C193 incandescent bulb available at this time. If you wanted to replace it with an LED light, the 906/921 LED Light Bulb - Wedge Base - 360 Degree - 215 Lumens - Cool White - Qty 2 Item # DI48VR can be used to replace the 193 or the 194 light bulb, among others.

  • Is the Bulb Replaceable in the # CR-007 Brake and Tail Light Trailer Hitch Receiver Cover
    Yes, the bulb in the Pilot Brake and Tail Light Trailer Hitch Receiver Cover, item # CR-007, is replaceable with a Replacement Light Bulb, item # 1157. Just pop the lens off from the front bottom right hand side and the bulb can be easily replaced. You may also be interested in a receiver lock to secure the brake light in your trailer hitch. The Trailer Hitch Receiver Lock, item # e98880, would be an excellent choice. We a a video demo of this item for you to review, see link.

  • Is There a Difference Between 2057 and 1157 Bulb for Trailer Wiring
    The 2057 and 1157 bulbs are interchangeable with the difference being the brightness. The 1157 is just slightly brighter than the 2057. For a replacement 1157 we have the # A1157B which would work great and would be your best option.

  • What are the Correct Replacement Bulbs for Optronics Trailer Lights # ST6RB and # ST7RB
    It looks like you have Optronics Lights # ST6RB and # ST7RB. For either of these lights, the correct replacement bulb will be # A1157B that you have referenced and # 30-90-194 for the side light. Trailer lights are a 2-wire system. This means that they have combined stop and turn signals on the same bulb. If the lights do not blink with the turn signals, you may need to change the running light wire with the stop/turn signal wires. Use a circuit tester like # PTW2993 to test the trailer...

  • Recommended Replacement Light for Wesbar Trailer Light
    The Wesbar Submersible Low Profile Trailer Tail Light # 403076, which you referenced, uses the replacement Light Bulb number 1157. That part number is # A1157B. If you have a different taillight and you can provide the part/model number I will be glad to find a replacement bulb for you.

  • Is the 4-Way of the Standard Trailer Light Kit # TL29BK Compatible with OEM 4-Ways on Vehicles
    The 4-way of the Standard Trailer Light Kit # TL29BK that you referenced is the standard trailer wiring 4-way that is found on most trailers that would also be compatible with an OEM 4-way trailer wiring harness on a vehicle. They use a standard 1157 bulb. For a replacement you would want the # A1157B. The gauge of wire in this kit is 18.

  • Replacement Square Submersible Tail Lights for a Karavan Boat Trailer With Replaceable Bulbs
    I recommend the Tail Lights # ST5RB for the drivers side and # ST4RB for the passenger side. These lights are incandescent so you can replace the Bulb # A1157B should it burn out. The lights are submersible and the main lens is 4-9/16" x 4-9/16" square. The drivers side light has an additional lens on the bottom of the light which will illuminate a license plate on the Bracket # BK31BB.

  • Solution for Trailer Wiring Light Assembly with Sealed Internal Capsule
    The older generations of the Wesbar submersible low-profile lights came with sealed light bulb capsules that are not replaceable. If your capsule is sealed, then your best option is to replace the lights with new lights like part # 403026 and # 403076. The new lights come with capsules that allow you to replace the bulbs. The bulbs used in these lights are # A1157B.

    The Optronics replacement bulb, # A1157B (or 1157) are dual filament bulbs. The double-filament design works for combination brake, tail and turn lights. You can also use # ARC85FR for a LED upgrade. The 2057 bulb that comes in some light fixtures is not as bright as the 157 bulb.

  • Fitment and Parts Included for Wesbar Trailer Lights 403026 & 403076
    Yes the Wesbar left side trailer light # 403026 and the right side # 403076 are the correct replacements for the Wesbar light you referenced and they will come with bulbs already included. What makes these different than the old generation Wesbar light, is there is no longer a replaceable capsule that contains the bulb that needs to be replaced. You will only need to replace the bulb itself because the unit is now sealed. If you are in need of a replacement bulb for this unit that is...

    Changing the bulb is simple. Remove the screw on each corner of the front of the lens and gently pry the lens away from the housing. Be careful not to damage the gasket between the lens and the housing as doing so will allow water into the interior of the lamp. With the lens removed, you can push in on the bulb and twist it clockwise then pull the bulb free. Install the replacement # A1157B bulb in reverse order..

    With your base having the same color wires you are going to need to bench test it with a Bulb # A1157B to verify which wire powers each of the filaments in the bulbs. The manufacturer should have used different colored wires like the Roadmaster # RM-155-2 which has black for ground, red for brake/turn and brown for running lights.
