A plastic joint for an automotive lamp assembly (10) has a housing (14) containing a tongue (20) and lens (12) containing a groove (18) to accept the tongue. The tongue or the groove can provide a channel for a thermoplastic material that is a bonding agent between the tongue and groove. The channel can also be formed by making the tongue narrower than the groove or by providing protrusions or depressions on the tongue or groove. The joint is formed by assembling the housing and lens and injecting the thermoplastic material into the channel in the joint. When the thermoplastic material cools, a bond is formed between the tongue and groove that fastens the lens and housing together. |
